    Type tested regulation number.

    Does anyone know the reg number that states that you can't mix protective devices? I have searched the forum but the search tool isn't great. Thanks

    DB installed connected & tested

    Just your thoughts on this DB,it’s a Lewden type,I personally don’t like them. Bus bar,not ideal,main switch on right,space very tight to make connections,hate the rcbo’s,screws in front of each other,making it hard to retighten .

    Earth wire on domestic heating oil tank - various questions

    Hi all I had a new consumer unit fitted 3 - 4 years ago. I was never told that I had to periodically test the RCDs by pressing the T buttons. Still, you live and learn! Anyhow, it is a split unit. The left side tripped when I hit the button. But the right side didn't. Did a bit of reading but...

    Just a general question on testing when carrying out a fixed wire test of 20% would you fill in all circuits identified on the circuit chart and test the required 20% filling in the results as tested or would you only fill out the circuits that you have tested and fill in N/A for every...

    Interesting Fault

    Had a call out yesterday to a house where the rcd on a board supplying storage heaters would trip intermittently. When I arrived the rcd would not reset at all. The rcd was also the main switch for the board. Obviously an earth/neutral fault I thought, so with all the mcbs off and the the rcd...

    Hello all.. I have a problem with a tripping RCBO and it has me stumped! Yesterday I fitted 10 RCBO's into a CU which currently had an RCD main switch. This was a sub circuit from a house CU which feeds various circuits for a cattery. 4 of the RCBO's are for the cattery pens. Pens 1,2,3 and 4...

    Testing IEC Extensions

    Hi all and thank you for letting me join the forum !! I do a bit of Pat testing at my work and have been asked to test some of the leads that attach to the IEC leads with the plug on(I.e. to make them longer). As these haven't got their own plugs do they have to be tested as surely they are only...

    What was the fault??

    I have been fault finding today. The problem was fairly common. 3 switches (on different landings) switching one light, so 2 2way switches and an intermediate. The problem was that sometimes each of the switches worked and sometimes they didn't, so sometimes you have to go back upstairs and...

    What could cause my voltage to drop to 28V??

    Evening all.. I have just tested a cable that I had put in place myself for a smoke detector and I am only getting 28V L-N. I am getting 240V L-E. When I first put it in it tested 240V. Since then the builder has been in and put the ceiling up, I'm not saying this is the cause but this is the...
