Penningtons Group's Premier Commercial Fuse Boards and Consumer Units Services

According to, in the year to 14th June 2020, Fire and Rescue services in England attended 28,447 fires. Of these, 13.5% were caused by faulty appliances and leads, 12% were caused directly by faulty energy distribution, and 30% were caused by the misuse of equipment of appliances. In this latter category, many fires would have been prevented if up to date circuit breakers had been installed.

To stay safe, it really pays to make sure your electrical circuits function properly and are equipped with the safety features set out in current regulations. If you are a commercial landlord it is essential that you ensure the electrical infrastructure of your properties is safe and meets current standards.

If you’re planning renovations, or your property has out of date fuse boxes and untidy wiring, a replacement fuse box (a fuse board or distribution board, and now in the industry generally called a Consumer Unit) will provide a safer and neater solution than older equipment.

In most cases a new CU will not need changes to existing wiring elsewhere in the property and can be carried out with minimum disruption.

Replacement Fuse Boxes have RCDs

The current, 18th, edition of the Wiring Regulations, Requirements for Electrical Installations, requires all circuits in a domestic property to be protected by a Residual Current Device (RCD). An RCD is a life saving device which is designed to prevent you from getting a fatal electric shock if you touch something live, such as a bare wire. It does this by preventing accidental earthing through contact with a live wire. It can also provide some protection against electrical fires.

RCDs are built into up to date Consumer Units (replacement fuse boxes) to protect people and circuits in the whole property. We prioritize the installation of Residual Current Devices (RCDs) in commercial properties.

Replacement Fuse Boxes have MCBs

MCBs are Miniature Circuit breakers. They protect against overloading or short circuits. In contrast to ‘traditional’ fuses, they are not destroyed when activated – they simply switch to off and isolate the affected circuit or appliance. Having these built into a Consumer Unit also provides the facility to isolate individual circuits within a property.

At Penningtons Group, we offer expert installation and replacement of MCBs to ensure the safety and efficiency of your commercial property’s electrical infrastructure

RCBOs add another layer of safety protection

An RCBO is an RCD complete with overcurrent protection – it’s a residual current circuit breaker with overcurrent protection.

This means that it will disconnect electrical current in the event current is unbalanced – effectively protecting against both overloading, and earth leakage current hazards. For example, the earth leakage protection cuts in if someone accidentally touches a live damaged power cable; the overload protection is activated when a circuit is overloaded with too many electrical devices.

An RCBO can be attached to each separate circuit in a property independently, meaning that a fault in one circuit will not affect the functioning of the others.

Surge Protection for valuable equipment

Modern electrical equipment, on which we all rely more and more, can be vulnerable to fluctuations in the voltage of mains electricity.

Some surges are obvious, such as flickering lights during a thunderstorm. However, many surges – often only lasting milliseconds – are not noticed. But frequent surges in voltage can damage equipment like computers and televisions. Even if damage is not apparent, the reliability and lifespan of the equipment is reduced.

Surge Protection devices come with different specifications. Pennington’s can advise on the most appropriate for your property and instal the ones which will best suit your needs.
