9 Best Whole House Surge Protector that Everyone Needs

    Whole House Surge Protector – Have you ever stopped to think how much of your daily work is dependent on electricity? From the geyser in the washroom to the microwave oven in the kitchen, you use electricity and electric appliances. Can you imagine a single evening without the tube light or a single summer day without the ceiling fan?

    Naturally, wherever there is electricity, there is a possibility of a voltage spike or voltage fluctuation. And continuous, not- monitored voltage fluctuation would mean damage to your electrical appliance. We wouldn’t want that, would we? A surge protector is exclusively meant to prevent such a situation.

    A surge protector alternatively called a spike suppressor or surge suppressor is a specially designed appliance or device. It is meant to protect electrical appliances from sudden voltage spikes.

    A spike is known to be a transient event, lasting for up to thirty microseconds. However, spikes are generally of the very high voltage value. So a few seconds are enough to cause intense damage to the electric appliance. For example, switching off a motor can give rise to a voltage spike of 1000 volts. Spikes can in fact happen on data and telephone lines. This is when the alternating current (AC) lines connect to the data line or because of lighting. (yes they can happen that easily.

    If these voltage spikes are ignored and the appliances left unprotected over a long duration, fuses and overvoltage relays might be unable to handle them and cause the appliance to break down. A surge protector evens out or blocks these voltage surges by using inductors. They inhibit to a large extent, sudden changes in current.

    By now you must have realized how important it is to have surge protectors for your electrical appliances at home. They come in different types and you will need to choose the best whole house surge protector that suits your domestic needs. In this article, we have covered the different types of surge protectors. We also have for you, an overview of the best whole house surge protector for 2021.

    Why do you need a surge protector?

    Even if it is not common in your region, you must definitely have heard of a voltage fluctuation or a voltage spike. In case of a voltage spike, more Current flows through an electric circuit than is safely permissible. If more current is provided to an electrical appliance than it can handle, it can be damaged temporarily, or even permanently.

    A surge protector acts as a mediator. Whenever there is a voltage spike in the circuit due to a lightning event or any other fault in the circuit, the protector absorbs the spike. They contain a Metal Oxide Varistor (MOV). The damage that would have been caused to the electrical appliance is now transferred to the surge protector. The surge protector works by blocking any electricity above the safe threshold that passes through the circuit, which is usually above 120V. Over time, the MOV degrades until it is reduced to just a basic power strip. However, it does work efficiently.

    Regardless of whether your area lies in a frequent lightning region or not, you can never be too careful about a voltage spike. They can happen at any time, unexpected, and a huge enough lightning spike will be successful in destroying any costly piece of electronic equipment. As you increase the use of electronic devices in your life, it is imperative to increase their protection too.

    Thus you need a whole house surge protector to protect all the electronic devices from sudden voltage spikes and fluctuations in your domestic space. Whether or not you live in an area that is subject to frequent lightning or frequent voltage spikes, precaution is better than cure. It is always a wise and safe idea to incorporate a surge protector in your household circuit in anticipation of a voltage spike and consequent damage.

    Whole House Surge Protector – Buying Guide

    House surge protectors protect electrical equipment from spikes in voltage. They cover the whole house by limiting the voltage that can enter an electrical appliance. It does this by simply blocking the current or shorting the excess current to the ground. Surge protectors are very different from extension leads, plugs, or towers, which only protect parts of the house.

    There are various reasons for a surge in voltage. They can happen anytime, and you must always prepare yourself. Hence, protect your house using the best whole house surge protector for 2021 and avoid expensive repairs later on. Prevention is still better than cure and added expenses.

    It would help if you considered the following factors before purchasing a whole house surge protector.

    NEMA Enclosure Type

    NEMA is the abbreviation for National Electrical Manufacturers Association, responsible for providing a set of regulations and standards concerning electrical devices. Many whole house surge protectors are of NEMA type. They can also be of different types depending on whether they protect against dust, oil, water, etc. So while installing the surge protector, make sure that the enclosure suits the location.

    UL Certification

    Whole house surge protectors should always be UL certified. UL stands for the (formerly) Underwriters Laboratory. UL has been certified to perform security screenings by OSHA. OSHA is a US federal company and is the abbreviated form of Occupational Safety and Health Administration. It provides the list of testing laboratories that are Nationally Recognised Testing Laboratories.

    Although various regulations exist, UL 1449 3rd Edition is the highly recommended set of safety standards for SPDs (surge protective devices). Your whole house surge protector should be UL 1449. The UL certification is mentioned on the SPD itself, but you must contact the manufacturer before installing it if it’s not.

    Maximum Surge Current Capacity (MSCC)

    Maximum Surge Current Capacity is a rating used to represent the maximum surge current that can flow through an SPD safely, without any external damage. Not all SPD devices state the MSCC rating, but we advise you to check it once. Commonly, nominal discharge current ratings are written on the SPD devices instead of MSCC.

    Maximum Continuous Operating Voltage (MCOV)

    You should not confuse MSCC with MCOV. MCOV stands for Maximum Current Operating Voltage. It is also a standard rating, which means the maximum steady voltage is applied safely on a mode of SPD. The voltage should always be according to the MCOV rating because if it is higher than the mentioned one, it can lead to electrical fires.

    Clamping Voltage

    Clamping voltage is the quantity of voltage that can pass through an SPD before the SPD clamps or limits the passing of more voltage to the electrical device it is protecting. A whole-house surge protector, for example, restricts a 6000 V surge. Then only a load of 600 V will be visible to the device. Then the clamping voltage is 6000 V. Clamping voltage can sometimes be too expensive. In this case, the surge protector lets in more voltage than the specified value, which breaks it.

    The clamping voltage should not exceed the operating voltage of your device. So remember this point while looking for the best whole house surge protectors. Or you can purchase devices with clamping voltage less than 700 V to be on the safer side.

    Diagnostic LEDs

    We use diagnostic LEDs to check if the whole house surge protectors are working correctly. During purchase, make sure that the diagnostic LEDs come along with the whole house surge protectors. They will help to check the power, protection, and line fault status of the SPDs.

    EMI/ RFI Noise Filtering

    EMI and RFI are very different technical terms but can be treated the same in whole house surge protectors. EMI is Electromagnetic Interference, whereas RFI is Radio Frequency Interference.

    Filters allow only particular frequencies to pass through while restricting others. For this, we use low pass filters, high pass filters, or bandpass filters. They serve the purpose of transferring the required EMI/ RFI emissions to the gadget that the SPDs are protecting. These emissions do not interfere with the gadget’s working and frequencies.

    EMI/ RFI serves the purpose of noise filtering. When they reach the whole house surge protectors, they remove electromagnetic or radio frequencies that might interfere with the device. So always select SPDs with EMI/ RFI emissions.

    Desirable features and functions in Surge Protector Devices (SPDs)

    These are some of the features and functions of whole house surge protectors that are found in different types of devices.

    These are some of the features and functions of whole house surge protectors found in different types of devices.

    • Automatic power shut off

    The automatic power shut-off feature is only found in a few models in the market and can be highly beneficial. When the voltage or current exceeds the maximum surge protection capacity, it damages the SPD. Then this function shuts off the power to all the outlets in your home. This function preserves all the electronic devices that you connected to outlets. But it will also shut down the wireless or broadband routers, which can be a disadvantage.

    • Inbuilt diagnostics capacities

    The best whole house surge protector models come with inbuilt diagnostic LEDs. It helps understand the right way to ground wires, connect gadgets, check the availability of outlets, etc. The diagnostic LED must meet all your requirements. So purchase SPD after cross-checking for them.

    • Eliminating phantom load

    Phantom load is nothing more than standby power. It uses up electric energy if the devices are not in use. It is a kind of electric leakage. All house surge protectors with power-saving options protect the appliance by automatically stopping power flowing from your device by turning off the master outlet.

    • Inbuilt safety covers

    Whole house surge protectors must come with safety covers to protect the children of your house. Children are curious beings and can poke their fingers in the device if it is within easy reach. It may cause electric shocks or even something more severe.

    • Selection of wattage

    People who work with multiple devices simultaneously, like desktop, laptop, peripheral devices, must look into this feature before purchasing the best whole house surge protector for 2021. It provides a network switch and the selection of wattage that a particular device requires.

    Price and warranties

    Types of whole house surge protectors

    Whole house surge protectors are also of various types, with each type having its own set of functions.

    Type 1 SPD

    A Type 1 SPD is used to protect your house and gadgets from lightning or problems caused directly by the power company. It defends your home from all power surges that are straight from the grid. It uses a spark gap technology and discharges a current in a waveform of 10/350 microseconds. You must install Type 1 SPD at the entrance of your house. Make sure to put it on the “line side,” which lies between your apartment’s power meter and the utility pole.

    The power company has to directly install the Type 1 SPD, which can be a disadvantage. They shut off the service panel before proceeding further.

    Type 2 SPD

    Type 2 SPD is the most commonly used whole house surge protector and is also called the panel protector. It protects all the circuits, along with the sub panels of your house. It works on the MOV (metal oxide varistor) technology and has an 8/20 microseconds current wave. So you need to install it at the break panel. It then branches the power to the house’s various service panels, as it is directly connected to a dual-pole breaker.

    Type 3 SPD

    Type 3 SPD is used in addition to the already installed Type 1 or Type 2 SPD to provide extra protection, as they have low discharge capacity. You must install them all around the house at the points of use. It plugs directly into the power outlet, which gives you the chance to plug in your electronics in the SPD itself. It provides maximum safety from sudden power surges. Type 3 SPDs have combined waves of voltage (1.2/50 microseconds) and current (8/20 microseconds). They are inexpensive and prevent damage to your devices or home.

    Frequently Asked Questions (FAQs)

    Q1 Where should Surge protectors be installed?

    Surge protectors are meant to protect all the electrical appliances in your home. Any electrical appliance might face a voltage spike at any given time, so your ideal surge protector will cover all the electronic devices that you use at home. Thus, if you go for a whole house surge protector (that is recommended) it will be installed at the main panel or meter at your house.

    Q2 We have never experienced damage to electronic appliances due to voltage spikes. Why should we use a surge protector?

    You can never really be sure about a voltage spike. A voltage spike can happen at any time, because of lightning, or because of any fault in the circuit, or otherwise. Often some voltage spikes are small enough not to be noticed and they cause damage over a long time. Thus, it would be wise and safe to use a whole house surge protector to be ready for any kind of voltage spike.

    Q3 Will a surge protector help to reduce my electricity bills?

    Unfortunately no. Surge protectors are not designed to be energy-saving devices. They are meant to be used as insurance to electrical appliances against damage from voltage spikes, by evening them out. That is the only function they perform. However, a good surge protector from a trusted company will protect your electrical appliances for quite a long time, so that is a huge plus point to be considered. So, even though surge protectors have no direct relation to your electricity bills, they are a wise option to opt for.

    Q4 Will whole house surge protection be very expensive to cover?

    Actually, no. There are different types of surge protection devices available in the market in different price ranges. You can choose the best whole house surge protector that will fit into your budget and at the same time, fulfill your domestic requirements. Especially in areas with frequency lighting, voltage spikes are very common and can happen almost every day, causing extensive damage to domestic electrical appliances. When you compare the cost to your electronic devices because of voltage spikes to the cost of surge protection, you will realize that it is actually very economic.

    Q5 How long can I use one surge protector?

    The better quality surge protector that you purchase, the longer it works and lesser the expensive equipment you have to buy. The lifespan of a surge protector also depends upon the amount of voltage spike it is absorbing. This will vary from place to place and from household to household. You can also not understand for sure when your surge protector has degraded and has turned into just a basic power strip. However, on average, for all areas, changing the surge protector once every two years is a good idea. A good surge protector will have the capacity to endure for at least two years.

    However, if you have a feeling that your surge protector is taking a bigger hit than usual, you can change it more frequently too.


    Over the course of time, we have come to realize that electricity has become an indispensable part of our lives. At the same time, we must recognize that no matter how useful, electricity is definitely a dangerous source of energy.
