A five fused fusebox in friends garage (non rcd box) is supplied from an rcd'd box in his house. The garage box supplies, 2 fountain pumps
1 cesspit pump garage doors, sockets and lights pool pump etc And auto gatesOn friday his gates tripped the rcd (continues to do so) Mr autogateman finally blames one motor even though his meter finds no fault.
when the rcd was put back on neither the cesspit pump nor the fountain pumps worked but garage doors sockets and lights ok
finally after tripping all switches in the garage box and turning on one by one all starts to work again (not auto gates) until the next day when cesspit overflows.
pump extracted, floats shaken a little, nothing. cesspit pump box (seperate from fuse box) has a tripper switch off/on...pump works.
The question is are all these things related? If not are pumps and a motor really all expiring at the same time? Is there any fault in a fusebox/supply that can display these problems. Why can I switch the fountain pumps on then nothing, change nothing other than having all other trippers off then switch it on again and they work.
House is less than 10 years old.
Many thanks
