Pond pump

[peteelecs]

I am having problems with a pond pump the RCD will trip after about 10 minutes every time I reset it but the mcb does not trip at all any advice would be appreciated

How, and where, is the pond-pump lead connected to the supply?

 

[peteelecs]

downstairs ring main 3 pin plug in socket outlet

So, I take it the pond must be very close to the house?

How does the cable run to the pond?

Have you had a very close look at the cable?

Sounds to me like the pumps had it

there is something wrong you have any earth neutral fault on the line do PAT test on device that will tell if that is problem

Sounds like cable extentions and buried leads to me.

Don't let the horse's out.

 

[peteelecs]

cable goes through wall then buried all the way to pond

Go for the pump first time every time. Look elsewhere once you proved it's ok.
Disconnect the pump completely and then disconnect at the CU then IR test the cable.

Hi
I installed a feed to a pond pump via swa from ring indoors via rcd unit last year it all tested up with no problems had a phone call recently they said
every time i switch pump on via isolator outside the rcd unit trips !!!!!!!!!!!! I asked questions and found out they had baught a second hand pump from ebay !!! and it was knackerd one lesson learned when i check faults allways go for the simple solutions and d,ont all ways reach for your test gear as a lot of faults can be found visually
