FAQs

Are all consumer units metal now?

Most new consumer units installed in domestic properties are made from metal in order to comply with current UK wiring regulations. Metal enclosures typically provide improved fire resistance and enhanced electrical safety.

Should I use RCBOs or RCDs?

RCBOs provide individual protection for each circuit, so a fault affects only the affected circuit. RCDs protect multiple circuits together, making them a more cost-effective option, although a single fault may disconnect several circuits.

What consumer unit should I install in my garage?

A garage consumer unit is usually more compact and designed to supply lighting, sockets and power tools. The correct size depends on the number of circuits and the electrical load required.

Can I install a consumer unit myself?

Replacing or installing a consumer unit should only be carried out by a qualified electrician. The work must comply with current wiring regulations and usually requires inspection, testing and certification post installation.

Do I need surge protection in a consumer unit?

Many modern consumer units include or support surge protection devices (SPDs), which help protect electrical equipment from damage caused by power surges. Whether surge protection is required depends on the installation and current wiring regulations.

What’s the difference between Type A and Type AC RCDs?

Type AC RCDs detect alternating current (AC) faults only, whereas Type A RCDs detect both AC and pulsating DC fault currents. Type A RCDs are generally recommended for modern electrical installations with appliances such as washing machines, EV chargers and induction hobs.
