I recently had to have my Hotpoint washing machine repaired.
When the engineer arrived, he said that under new rules he had to do an
earth leakage test on the house electrics before he could do the repair.
He plugged in a tester and said, oh dear, it's more than 200 Ohms. He tested
various circuits around the house and still it was more than 200 Ohms.
I asked him what it all meant. His reply was very vague, in so much as his
reply was, he knew there was an earth, but it was more than 200 Ohms and
really he shouldn't repair the machine until such time as it was put right
and I would have to get an electrician in.
After chatting with someone on the phone he eventually did the repair.
My earth is provided by a metal rod sunk into the garden which is under a
flagstone and a green cable from that to a terminal block and then to the
fuseboard. All connections are tight.
In between the meter and the fusebox is a Residual Current Operated Circuit
Breaker, 204V 50Hz 80A Load to BS4293, Model WSES 80/2 30mA Trip.
At my previous house, we had one of the former (Similar) with an earth cable
attached to that as well as an earth rod.
I have just be reading about different types of earthing systems.
My questions are these:-
Which earthing system have I got ..... ?
Although I have an earth, what was he on about ..... ?
I always thought that if you had a earth it was okay.
Should I be unduly worried ..... ?
Could it be that the earth cable at the earth rod has come off some how by
Electricians are expensive and I want to explore every possible avenue
Your help and advice are most welcome.
