Electrical fire risks often begin with small warning signs: hot sockets, repeated tripping, damaged insulation or overloaded extension boards. These are not problems to ignore.
Common causes of dangerous heat
- Loose terminals inside a switch board or socket.
- Undersized cable used for a heavier load.
- Too many appliances on one extension board.
- Damaged insulation, exposed wire or moisture near a connection.
- Replacing a protective device without finding the cause of repeated tripping.

What to do if you notice a warning sign

FAQ
Does an MCB trip for no reason?

When should house wiring be inspected?
Arrange an inspection after recurring faults, visible damage, renovation work or unusual heat at fittings.
