Hiya Guys,
I hope there is someone out there who can answer my problem. I'll do my best to explain my situation.
Right then - I have been given the task by my employer to test/inspect some Distribution boxes.
(Here is a link from a random web site I found showing the boxes - Electrical Distribution Hire | Gofer Ltd - Event Power )
Before I go any further, I'd like to point out that I'm not actually fully qualified but in training at adult classes during the evening at my local college.
I work along side two fully qualified sparks, who are suppossed to aid me, but they'd much rather laugh at my efforts and fails. Hence me asking in here, and saving myself being patronised or critisised.:banghead:
So I'm doing the continuity test, R2 to R2 etc, L1 to L1 etc. Testing the sockets one by one. When I test my first socket from incomer L1 to outgoing L1 it passes with an expected 0.00 ohms (or there abouts) but when I come to test my second socket, from incoming Line to outgoing line, my RCBO trips. It'll even trip when testing continuity on the neutral.
Can someone please explaing why some breakers will trip, and others will be OK. Bearing in mind that most of the boards I test are 63A Single Phase incomer with the outlets being a mix of 16A and 32A Single Phase.
Other boards I test are 3 Phase incomers with 16A single phase outlets and 32A Single Phase outlets.
I just can't seem to get my head round it.
Also - just to add - Conntinuity is good from the incomer, to the bottom of the RCBO, and is also good from the top of the RCBO to the outlet. But to go from the incomer to the outlet, going through the breaker is a no no as it trips (on some but not all). Gutted.
Also like to add that these are all new RCBO's. Fresh out of the box.
Thanks Guys!!
