Keeping electrical safety in check

Keeping electrical safety in check

Why does your fuse board keep tripping?

20th November 2025

Employers have a duty of care to provide safe working conditions, and landlords must ensure their properties are safe for tenants, and it goes without saying that that includes electrical safety.

If a fuse board frequently trips, it’s a sign of an electrical fault and should be investigated promptly to protect everyone who’s using the building.

Why do electrical circuits trip?

As mentioned, a tripped circuit is usually caused by an electrical fault of some sort. Some issues are easy to identify and fix, while others will require a qualified electrician with specialist diagnostic equipment.

Common causes include:

  • Overloaded circuits
  • Blown light bulbs
  • Water in exterior electrical fittings
  • Incorrect DIY electrical installations
  • Faulty heating controls or appliances
  • Misused or overused appliances
  • Faulty appliance connections
  • Too many appliances running at once

Sometimes, simply switching the tripped fuse back on will restore the power. However, if an underlying fault exists, the issue will keep recurring and should be inspected by an electrician.

The role of PAT Testing and Fixed Wire Testing in commercial properties

To meet legal obligations under the Health & Safety at Work Act 1974 and the Provision & Use of Work Equipment Regulations 1998, electrical equipment must be inspected and recorded through Portable Appliance Testing (or PAT) testing. PAT testing follows the IET Code of Practice for the In-Service Inspection and Testing of Electrical Equipment (5th Edition).

Fixed wire testing, on the other hand, inspects a building’s entire electrical installation. After testing has been carried out, property owners receive an Electrical Installation Condition Report (EICR), ensuring compliance with the Electricity at Work Regulations 1989 and confirming that all the wiring is safe.

Both types of testing are vital to preventing electrical fires, injuries and other safety risks.

At MS Electrical, we offer out-of-hours fixed wire testing to minimise disruption and send reminders when your next inspection is due, helping you stay compliant. Contact us to book your PAT testing or fixed wire testing, or to request a no-obligation quotation.

Testimonials

The engineer was on time (early) and offered a friendly, efficient service. He worked tidily and quickly, testing all electrical appliances around our building and offices. He wasn’t afraid to challenge where due, which only added to his conscientious attitude – I felt safe in his hands. Would recommend MS Electrical to you.
