It could be one of the heaters, anything with a heating element is prone to causing these sort of trips. I would unplug everything you can and switch everything else off for one night and see what happens, really needs an electrician round to test the actual circuits though to eliminate them.
Common reasons your breaker keeps tripping include circuit overload, a short circuit, or a ground fault. The following information will help you understand the differences between these three reasons so that you can better resolve your circuit breaker and electrical system issues.
If your main circuit breaker switch keeps tripping in the night and you can see that it's the immersion heater trip switch that is off, it's more than likely that the immersion heater element has gone and needs replacing.
Open the cover on the consumer unit to see which switches have tripped to the OFF position. Put them back to the ON position. If tripping occurs again, it is probably being caused by a faulty appliance. You need to identify which circuit is affected and which appliance on that circuit is causing the problem.
If your circuit breaker is regularly tripping out, this indicates that you are demanding too much power from the circuit. In this case, you need to redistribute your appliances and devices onto different circuits, or even upgrade your system if it just doesn't have enough circuits for modern demands.
If the circuit is not overloaded and the breaker keeps tripping, it is essential that you immediately contact a professional electrician to determine the source of the problem. With a short circuit, you will usually also notice a burning smell or even see smoke.
Electrical overloads are the main cause of breaker trips. Limit the number of devices plugged into the same circuit to avoid tripping the breaker. That might mean moving a few appliances or devices to another circuit or simply unplugging something.
If the breaker trips immediately upon resetting, even with nothing plugged in or turned on, it's likely something in your home's wiring causing the problem. This could be a loose connection at a receptacle or other device, or something more complicated, like worn insulation within your walls.
If your fuse box keeps tripping, it means that the circuit breaker or fuse has blown because of overload. This may be caused due to number of things. But there are several things to cut the problem. So that you don't end up replacing good electrical items.
A tripping circuit breaker can be frustrating – and dangerous. Those flickering lights and dark rooms could pose a fire risk. If you've lost power to a part of your home, you'll probably need to call a professional, since working with electricity can be highly dangerous.
A circuit breaker can fail without tripping and is an indication it needs to be replaced. It can also mean there are wiring issues with the circuit itself, such as exposed/loose wiring, overheating, and unregulated voltage.
Before resetting a breaker, you must determine the cause of the trip. It is safe to reset a breaker only if it has been determined that the circuit was overloaded. Repeatedly resetting a breaker could result in an arc flash or a fire.
This particular solution is simple. All you need to do is move an appliance or two from the overloaded circuit onto another circuit that can handle it. If that's not the case, then it's time to get in touch with a certified electrician.
Reasons your safety switch might trip
overloaded power sockets or power boards. faulty appliances. faults your home wiring. water in the walls or ceiling affecting the power circuit - Has it rained recently or is there a sprinkler hitting an outdoor power point?
The first step in finding a short circuit is to look for physical signs. This may include visible burns or melted metal on wires, burning smells, or flickering lights. Once you've identified a potential short, use your multimeter to confirm the voltage by placing it on its resistance or continuity setting.
A circuit overload is one of the main reasons for constantly tripped circuit breakers. This occurs when you want a particular circuit to provide more electricity than its actual capacity. This will lead to overheating the circuit, which puts all the electrical appliances connected to the circuit at risk.
Breakers that Trip Frequently
The circuit breaker trips due to overload. In older panels, you may also hear a cracking sound. This is a sign that you need an electrical panel upgrade. The circuit breakers are designed to turn off electricity to protect from overload.
That depends on its design, and how heavy the overload is or how near to its maximum rating it runs. Most breakers can survive a few dozen trips. If a breaker will not reset or stay set with the MAIN power OFF, it's bad, and needs replacement.
1. Turn off or disconnect in area of house that lost power. Before you head to reset your circuit breaker, turn off all light switches and unplug, turn off or disconnect important appliances and devices in the area of your home that has lost power.
Check for Damaged or Loose Wires
Having a wiring problem won't trip your breaker, but it'll certainly cause your light switch to work improperly. To find out if you have a wiring issue, you can remove the light switch from the wall—but only after you've turned off the electricity to the switch.
Just flip the breaker into the off position, leave it a couple of seconds, then flip it back into the on position. If this doesn't fix the problem, then you know it's one of two issues – it's either an isolated incident that isn't tripping the breaker, or the breaker itself is faulty.
