Do I need a new fuse box for an EV charger?

Many local residents in Bristol ask, do I need a new fuse box for an EV charger? Check out the guidance from Allied Electrical Services, a reliable and trustworthy electrician with 100% customer satisfaction.

Do I need a new fuse box for an EV charger?

An EV charger will require additional power load and this could cause great strain on your home's fuse box. Smaller appliances like the microwave or iron are often plugged in and used for short amounts of time. An EV charger on the other hand will probably be plugged in for around 8-10 hours to fully charge. This requires a fuse box to safely manage the additional demand as well as powering all daily appliances at your home in Bristol.

So a new fuse box or more commonly known, consumer unit will ensure the additional power demand is managed. Modern safety devices included in consumer units will provide advanced protection, keeping your household safe as the EV charger is used.

How do I know if I need a new fuse box?

Certain signs to look out for include frequent tripping when appliances are in use or if RCD protection is clearly missing from your current fuse box. If the fuse box at your property is outdated and includes rewirable fuses, an upgrade is a necessity if EV charger installation is on the cards.

Allied Electrical Services have over 25 years experience investing electrical systems in domestic dwellings. A quick inspection of the existing fuse board at your home in Bristol will help determine whether a fuse box upgrade is required.

Safety consideration when upgrading a fuse box for EV chargers.

EV chargers must be installed on circuits protected by devices such as RCD or Residual Current Devices. These devices switch off power within milliseconds to prevent damage or injury to individuals.

SPD or Surge Protection Device is another safety regulation in modern fuse boxes. These particular devices are particularly sensitive to spikes in voltage and divert excess voltage to the earth, preventing costly damage to the EV charger and other household electrical appliances and systems.

Why work with Allied Electrical Services.

Upgrading a fusebox in preparation for EV charge installation is considered major work, classed as notifiable work under Part P of the Building Regulations. Such work must be carried out by a qualified electrician to ensure compliance with standards like BS7671.

Allied Electrical Services are NICEIC approved electricians so we tick all the boxes. From our social media posts, you can see that fuse box upgrades are a popular service delivered by the team. We have the experience and can self certify fuse box upgrades as electricians from a competent person scheme such as NICEIC.
