#The surge 2 questions update

The March 2022 update makes these statutory or ‘advisory’ regulations more important than ever – now being mandatory for homes and commercial properties.

There may be damage to cultural heritage, such as records.

It may cause an interruption of commercial or industrial activity.

It could affect a large number of co-located individuals.

There may be an interruption of public services.

Overvoltage could result in serious injury or loss of human life.Since 2019, the IET Wiring Regulations have advised either fitting an SPD or performing a risk assessment in case: Thankfully, the Institute of Engineering and Technology (IET) understands the risk of overvoltage, and has taken steps to protect people and properties on a national level. The surge protection device absorbs this extra current and then disperses it naturally. If lightning strikes nearby, it could cause a rush to your electrical system damaging fuses, circuits and equipment. It protects your electrical systems in case of ‘transient overvoltage’, sometimes known as a power surge or overload.

Unlike what you might find on a power strip, the surge protection devices we’re talking about are installed on the property’s consumer unit, sometimes referred to as a fuse board/box, or sub-distribution boards. This is where a surge protection device (SPD) will help.īefore we get into the reasons for consumer unit surge protection, or the SPD requirements, we should first provide a little more background. Instead, the effects can be much more localised causing possible damage to your home’s electrical system and the devices you have connected at the time. While they might appear exaggerated, these threats do exist – just not typically on the ‘doom and gloom’ national level you’ll see in the cinema. They always cause wide-spread carnage, making for a better movie-going experience. Hollywood films show solar flares and electromagnetic pulses (EMPs) as world-changing events.
