Overload
Too many appliances on one circuit, such as a kettle, an oven and a heater on the same sockets. The breaker holds for a while, then trips once things warm up.Fix: move loads to another circuit, or add a new circuit for the heavy appliance.
Power that trips again and again is the DB board doing its job: something on that circuit is wrong. We find the cause, replace worn breakers and upgrade boards that are too small for the load in your home, office or shop.
A breaker trips for one of four reasons: the circuit is overloaded, there is a short circuit, current is leaking to earth, or the breaker itself is worn out. A breaker that trips again straight after a reset has a live fault behind it and should be left off until an electrician has tested the circuit.
DB stands for distribution board. It is the box, often near the entrance, where the incoming supply is split into separate circuits. These are its main parts.

Live and neutral touch, often inside a damaged flex, a burnt socket or a light fitting. The breaker trips with a snap the moment it is switched on.Fix: find the damaged part and replace it.
The ELCB trips, sometimes only when one appliance runs, or after rain or floor washing. Water heaters, washing machines and outdoor lights are the usual suspects.Fix: test each circuit and appliance in turn to find the leak.
Breakers weaken with age and heat. A weak one trips below its rating, feels warm, or will not latch.Fix: replace it with a breaker of the same rating and type.
A tripping breaker points at a fault somewhere on its circuit, so the repair often ends at a socket, a light fitting or a length of cable. If the board is sound and the cable is not, see electrical wiring and rewiring. For everything else our electricians in Doha handle, start at the main page.
An MCB protects the cable: it trips on overload or a short circuit. An ELCB, also called an RCD, protects people: it trips when current leaks to earth. A safe DB board has both.
The heating element sits in water, and when its coating fails a little current leaks to earth. The ELCB detects that and cuts the power. The heater needs testing, and usually a new element, before it is used again.
In summer every AC unit runs for long hours, so the total load is at its highest and the board runs hot. Breakers that are old, or circuits that were already near their limit, give way first.
A like-for-like change in an apartment is often done within a day. A large villa board with many circuits takes longer. The expected shutdown time is given with the written quote.
Yes, if the board has a spare way and the supply can carry the extra load. If the board is full, we quote for a larger board or a second one beside it.
Yes. Buzzing or crackling means a loose connection is arcing, and that produces heat. Switch off the main switch if you can reach it safely and call our emergency electrician.
