Whole-home surge protectors are designed to protect your home from dangerous lightning strikes that could knock out power or fry your electronics, potentially resulting in thousands of dollars in damages.  Recently, however, there has been a lot of controversy surrounding whole-home surge protectors, claiming they’re a waste of money and don’t do what they claim to be able to do. So what’s the real story here? Are whole home surge protectors worth it?

We’ll start by talking about what surge protectors are not designed for: protecting your home from all sources of increased voltage. Power surges most commonly originate inside your home as a result of different appliances turning on and off. Depending on your home’s electrical service (100amp vs 200amp or whatever you may have), you’ve probably seen this in the form of flickering lights when your air conditioner cycles on.

Whole-home surge protectors do protect your home from power surges that originate outside, commonly caused by lightning strikes but also resulting from any interruptions to the power: downed wires or utility poles, wind damage, utility repairs, etc.

There are a few different ways power surges can occur. Lightning strikes, which people tend to be most worried about, are actually pretty uncommon—conditions need to be perfect, and the strike needs to occur less than one mile away from your home. Despite their rarity, lightning strikes can send a 200,000-amp jolt through your home and are definitely not to be taken lightly.

The majority of external power surges occur when the magnetic field created by wires conducting electricity collapses, which sends large voltages down the wires and eventually, into homes and buildings.

Effectively defending your home from power surges requires a two-step approach: first, outfitting it with a whole-home surge protector, then using surge-protected outlets and power strips indoors. Both types of surge protectors act essentially like pressure relief valves, diverting excess energy away and restoring normal operation once levels regulate.

Whole-home surge protectors are usually wired to a service panel and are designed to stop surges of at least 40,000 amps, though larger ones can be installed. Pairing them with individual plug-in surge protectors should do a good job of catching any potentially damaging energy that may get into your home.

Like many safety-related things, whole-home surge protectors are appliances you buy and hope to never actually use. But all it takes is a single downed line or big lightning strike to cause thousands of dollars’ worth of damage to your home—not worth the risk!

About 80% of dwellings were built before the year 1990. While they may have complied with the safety standards at the time of construction, those standards might not be relevant in today’s day and age. Significant changes were made in electrical standards since 1990 and the protection technologies of today were not available or required back then. You must ensure that the standards maintained in such existing accommodations are raised to the electrical safety levels of the current standards.

Understanding the Risks at Existing Accommodation

Extensive safety studies must be carried out in the existing residential buildings to determine the disparity between the required safety standards and the existing safety standards. If the existing standards fall a little short, you must show an urgency to raise the level of safety of these buildings and bring them up to the current standards.

Thankfully, it isn’t too complicated or difficult to do so. You can take small steps to gradually improve the electrical safety through a program of manual safety audits.

3 Ways Current Safety Standards Help in Reducing Electrical Risks

Importance of Verification

The current electrical standards ensure that the new residential electrical installations are safe and that they remain so over their entire lifetime. IEC 60364-6 defines both initial verification of an installation as well as verification of residential dwellings every 10 years. The periodic verification ensures that the fundamental protective measures remain active and reliable.

Recommended Periodic Auditing

There must be periodic auditing to ensure that the safety conditions are up to the mark. The audits need to be simple and based on visual checks. They need to be performed by a qualified auditor, who can then inform the owner of any possible safety issues. The owner will then take responsibility for arranging any necessary repair work. The frequency of inspection can be defined by each country, either by a specific period (e.g., 10 years), or triggered by an event such as the sale or rental of a dwelling.
