Pond pump still tripping rcd

[peteelecs]

Pond pump is still tripping RCD which means I loose all power to socket outlets upstairs downstairs and kitchen (with freezer in it).Why doesnt mcb trip instead and what could be causing RCD to trip.Any advice would really be appreciated.

 

[dim_bulb]

is that all you did changed the fuse bs1362?
doesnt make sense why the rcd would trip you say everything goes upstairs/downstairs socket is this all on one rcd? could be accumlative leakage?

Last time I saw something like this the pump would pump for a few minutes and then trip the RCD. Turned out the pump was faulty and it was about 5 years old. New pump fitted and problem resolved.

pat test and do a load and leakage test , normally a fault like this is caused by water getting into the motor

Iknow it makes no sense but all i have done is change the fuse in the plug and it has not tripped since is this possible?

 

[Silly Sausage]

Maybe there was some moisture or something in the plug causing leakage, which you inadvertently removed when changing the fuse?

or a possible poor connection on the fuse/fuse carrier, causing a bit of arcing. only time will tell if that has solved the problem.

Place your bets please.

2/1 it will trip again within the next 48 hours.

5/1 its the pump on its way out.

9/2 its an accumulated earth leakage

10/1 all of the above.

Place your bets now .

New bet:

It will trip again in the night leaving the fish to swim around in thier own mess and all die 5/1 ?

Any takers

The fish will be fine, its the defrosted food that the home owner will kick off about.

Take it it's not a Koi pond then?

 

[Paul.M]

There's been no mention of fish? Oh maybe they have got an electric eel that's tripping the rcd? Ok I'm getting silly again, I bet its the motor.
