A Practical Electrical Maintenance Checklist for Your Home

Every two to three months

Test the RCCB

Press the test button on the RCCB at your distribution board. It should trip immediately and firmly. Reset it and you are done. If it hesitates or does not trip, the device has failed and needs replacing — this is the highest-value item on the whole list.

Walk round and touch things

Put a hand on the faceplates of sockets carrying permanent load — behind the television, the fridge, the washing machine, wherever a charger lives. They should be at room temperature. Anything noticeably warm needs attention.

Look at plugs and leads

Check appliance plugs for discolouration and leads for damage, particularly where a cable enters a plug or an appliance and where furniture might have been pushed against it.

Before and after the monsoon

This is the seasonal check that matters most in Surat, and it is worth doing properly at both ends of the season.

• Inspect every outdoor and balcony point for a sound cover and seal
• Check terrace and outdoor light fittings for cracked housings or perished gaskets
• Look for damp patches on walls where cables are known to run
• Take down any indoor-rated decorative lighting that is outside
• Confirm outdoor circuits are behind an RCCB — this is the season it matters
• After the rains, check the same points for water that got in and stayed

Annually — things you can do

1. 1Clean ceiling fan blade tops, supporting each blade from below
2. 2Tighten fan blade bracket screws and check the down-rod pin
3. 3Test every switch and socket in the house, including the ones nobody uses
4. 4Check that the distribution board is labelled and the labels are still accurate
5. 5Confirm everyone in the household knows where the main switch is
6. 6Look over any extension leads in permanent use and ask whether a proper point would be better

Annually — things that need an electrician

These require test equipment, isolation of live circuits, or both. They are the substance of a professional maintenance visit.

• Opening the board and checking every termination for tightness and heat damage
• Insulation resistance testing on each circuit
• Earth continuity testing to accessible points
• Earth pit or building earth condition, where accessible
• Load measurement across circuits, and across phases on a three-phase supply
• RCCB trip time verification, which goes beyond pressing the test button
• Inspection of fixed appliance connections — geyser, hob, AC isolators

The first item on that list is the most valuable and the least glamorous. Thermal cycling loosens terminals over years, and an hour spent checking and re-making them at the board prevents the overheating faults behind most domestic electrical fires.

When to bring the annual check forward

• After any water ingress — a leak, flooding, a burst pipe near a cable run
• After civil work, drilling or carpentry that may have disturbed concealed cables
• When you take possession of a resale property
• After any incident: a shock, a burning smell, a small fire, a violent trip
• When adding significant load, such as another air conditioner
• If tripping has become a routine part of household life

Keeping a record

Keep the reports from professional visits together, and add your own notes when something happens — a circuit that tripped, a socket that was replaced, the date you last tested the RCCB.

It sounds fussy and it is genuinely useful. An intermittent fault becomes far easier to diagnose when there is a record showing it happens on the same circuit every few weeks. It also makes a property considerably easier to hand over, whether to a buyer, a tenant or a different electrician.
