MCB Tripping

[Gordon_5112928]

My 10v MCB keeps tripping, some times when low power is being used (ie fire on 1000 watts) also when switching OFF the fire it will trip.

Any ideas ?

Hello Gordon,

Does it always happen with the same appliance, or can it happen with several different appliances.

If it is just one appliance every time, then I would suspect the appliance is faulty,

But if it can happen with any appliance, then it throws suspicion on the MCB its self, or possibly the caravan wiring.

Please remember that mains power can be lethal so for your safety and insurance, the fault must be repaired by a comment person working to the current wiring regs.

is it a baily caravan as i have heard some of their MCB's are faulty?

Gordon,

If your MCB is a 10 Amp trip - that's 2350 watts - so if you have something (maybe a kettle) rated at between 1500 and 2000 watts that will be a good stress test for the MCB.

Other than that, there is no easy way for a DIYer to check a faulty MCB, however a common MCB fault mode is for the MCB to start tripping on low currents.

It's probably worth changing the MCB.

Normally I would agree but it's a Bailey MCB!, I have found if faulty these MCB's will trip with the lightest tap of a small screwdriver handle!!

As far as I know replacements are only available through Bailey dealers

we had the same thing happen on our senator Indiana ,the hook up box kept tripping also ,so i phoned the dealer up ,and he told me to unplug the microwave ,allthough the microwave wasnt working there was an internal fault on the microwave which was causing everything to trip ,once i pulled the plug out every thing was fine , so after we got home had a new microwave fitted and its been fine since
