I know you are not supposed to do a insulation test on circuits that are protected by an RCD at 500v because it may damage the electronic components inside the RCD so that's why you switch the RCD off before you test the individual circuits, however, what if the circuits are all protected by...

So being very new to the industry I just wanted wanted a little guidience on testing a system...
So the system I will be testing uses 3 phase power, it also uses a single phase to power a variety devices, e.g. A pc, a temperature controller, power supplies. It has many circuit breakers...
Just wondering if anyone could shed some light on whether i am exempt from going through all the motions of initial verification again when i take my 2391 course and exams? Basically bagged the 2394 course for free just before it changed back to the combined 2391 and can't do the previous 2395...
Hi all.
I'm a 4th year electrician currently awaiting to finish my trade test. (FICA in Scotland) the only parts I have to pass is the testing part and fault finding.
I'm currently studying testing as this is something I have done the minimum of onsite.
Could someone tell me how I would...
Ok without any football team references... Mace are the managing contactor and spurs have nominated contactors. So mace wont be liable to any delay clauses due to this. I read in construction manager journal approx 500 sparks ( including supervision ) but not sure. Anyway my point is with that...
Hello all,
Perhaps a few of you could help my understanding of the following query.
The situation I am about to describe is purely hypothetical to help my understanding of the issue.
Let's assume within a domestic bathroom, I have a combination of exposed conductive parts and suspect...
Does it matter which method (method 1 or method 2) you use when testing for continuity of the circuit protective conductors? Or is each method dependent upon which the type of circuit you are testing on ring or radial?
I have been told that test method 1 is used for lighting and radial...
Is the continuity test for circuit protective conductors, the same test for ring and radial circuits or is there a different test for each type of circuit?
Also what is the difference between testing for cpc continuity and testing for continuity for ring final circuit conductors?

Hi,
Looking for electrical teams for rewire council occupied properties in London., Most properties are pull through and kitchen chased in., Price for teams or can do day rates for individuals , 6x rewires per day at the moment so lots of work for right persons/ teams,. Works are in Stockwell...
I've recently carried out a full rewire of a domestic property which had a supply to a garage by use of an armoured in ducting run underground. I have taken a new feed to the adaptable box that said armoured is terminated into and have tested the armoured itself and all is ok. My question is, as...
Hi everyone, still training so please bear with me.
What is the correct way to carry out an RCD test on a lighting circuit protected by a BS61009 Type B RCBO?
I've looked in the regs, OSG and all of my course material but still no actual definitive answer so thought I'd ask here.
The reason...
Good evening,
I decided to go out on my own several months back and have been extremely lucky winning all the work I have gone for. Things just got a bit more serious as I have been asked to Tender for a medium sized contract in London.
I have written estimates before but never actually done a...
