What to Check Before You Call an Electrician for Power Loss

Hi, I'm Anthony O'Brien, founder of AJOB Electrical Ltd. With over 20 years of hands-on experience serving homeowners and businesses across Leeds and Wakefield, I know how frustrating sudden power loss can be. The good news is, not every electrical fault requires an emergency callout! Often, a few simple checks can save you time, stress, and money.

Today, I'm sharing expert advice based on real-world experience to help you safely troubleshoot before picking up the phone.

1. Is It a Full Power Cut or a Localised Issue?

The first step is to determine whether the outage affects your entire home or just specific areas.

• Whole property without power? Check if your neighbours are also in darkness. If they are, it’s likely a supply issue. Call your energy provider to report the outage.
• Only certain sockets, lights, or areas? Then the issue is internal and most likely linked to a tripped RCD or MCB.

Anthony’s Tip: I once attended a job where a customer thought they had a full outage. It turned out only their upstairs sockets had tripped after plugging in a faulty hairdryer. A quick check could have avoided the callout!

2. Inspect Your Consumer Unit (Fuse Box)

Modern consumer units are designed with safety in mind and typically contain:

• RCDs (Residual Current Devices): Protect against electric shocks by cutting power if a fault is detected.
• MCBs (Miniature Circuit Breakers): Protect specific circuits, like sockets or lights.

What to do:

• Open your fuse box panel.
• Look for any switches in the 'OFF' position.
• If a breaker has tripped, that circuit has detected an issue.

Anthony’s Tip: Keep a small battery torch near your fuse box. In many cases, I've found customers struggling in the dark with just a mobile phone light!

3. Unplug Appliances to Isolate Faults

Faulty appliances are one of the most common causes of trips.

Here’s what to do:

• Unplug everything connected to the affected circuit.
• Reset the RCD or MCB.
• Reconnect appliances one at a time, leaving a few seconds between each.
• If the power trips again, you’ve found the faulty device.

Real Story: In one Leeds home, a persistent kitchen socket fault ended up being traced back to a leaking fridge causing short-circuiting behind the scenes. Unplugging it instantly solved the issue.

4. The Right Way to Reset an RCD

An RCD that won’t reset often signals a persistent fault. You can narrow it down safely:

Steps:

• Switch off all individual MCBs.
• Reset the RCD first.
• Switch MCBs back on one at a time.
• Watch closely: the faulty circuit will cause an immediate trip.

Anthony’s Tip: Take note of which circuit causes the trip. Telling your electrician this can dramatically speed up fault finding and may lower the cost of repairs.

5. When to Call a Qualified Electrician

If after completing these steps your RCD still refuses to reset, or if a circuit keeps tripping, it’s time to call a professional.

Serious issues could include:

• Damaged wiring hidden in walls.
• Moisture ingress from leaks.
• Overloaded circuits.
• Aging or faulty consumer units.
