    Upstream RCD's

    Hi all, I am currently planning on designing an installation for a conservatory to be fitted with lights, floor sockets, and underfloor heating. My plan was to take a 6mm T+E from the Hager consumer unit under the stairs, protected at 32A, which would then run above the ceiling of the room...

    Low N/E insulation resistance

    Yes I tested the cable before it was even connected to the terminals in the CU. I have just retested the circuit again and have now got 67 meg. Using a Fluke 1662 MFT. Not too worried just originally 26 didn't quite satisfy me as high enough for a brand new circuit. Thanks.

    Low N/E insulation resistance

    Hi all, Just installed a brand new radial circuit for the upstairs sockets with Prysmian 2.5mm T+E, around 21 metres in length. When testing the insulation resistance of the circuit upon connection to the consumer unit, I seem to repeatedly get around 49 Megohms when measuring Neutral to Earth...

    Varying continuity readings

    Not a lot really. Says how to zero the leads etc but that's about it

    Varying continuity readings

    I did sway towards this as I don't seem to get it when using the plug top test lead. Just wondering if anyone had experienced something similar before

    Varying continuity readings

    Hi all, I am using a Fluke 1662 with fused test leads. I find when doing continuity tests such as R1+R2, as the test button is being held the result fluctuates dramatically. Both increasing and decreasing. Seems to happen on insulation resistance as well however not so much. I also find after...

    Wooden shed heat detector

    I also thought it was unlikely, but not impossible. It's just the thought of it potentially going off for a long period of time before the residents return which would be annoying the neighbours that made me question installing it.

    Wooden shed heat detector

    Hi, I have been asked advice on installing a smoke detector inside a small wooden shed at the bottom of a garden, which is currently used for spray tanning. I have said that a smoke detector will be of no use as the mist from the machine will constantly sound the alarm. I thought I could fit an...

    Socket voltage readings

    They're double pole. The circuit was installed in around 1996 and I was told there has been no testing ever done on the circuit, even when it was installed. Someone said they were getting a small tingle when touching the socket. First thing I did was plug in this socket tester and received these...

    Socket voltage readings

    Hi all, Never seen this before. I am getting a red LED appearing on my socket tester without the socket being switched on, and then a 'No earth' from one socket tester but 'Live Neutral reverse' from another socket tester. I am also getting the following voltages at one of the sockets: Line to...

    Rcd/rcbo

    It is indeed for me so myself and the rest of my inhabitants will know about the arrangement.

    Rcd/rcbo

    Cable size is 4mm XLPE SWA.

    Rcd/rcbo

    Yes the sockets are wired with SWA so the cable and accessories are surface mounted. I had already thought of labelling each socket so it can be seen that those sockets are for the appliances that it is labelled for only. Thanks

    Rcd/rcbo

    Yes it's almost brand new. The consumer unit has a RCD protected side so I was going to put this circuit onto the non-RCD protected side so the food in the fridge freezer isn't lost if the RCD trips. What i'm not sure about is whether to put this circuit on a RCBO or a MCB with a RCD socket for...

    Rcd/rcbo

    Hi all, There is a 'utility' circuit in an outbuilding which feeds three 1 gang sockets in turn, one for a fridge freezer, one for a tumble dryer and the last one for a washing machine. What I am wondering is whether to put the circuit on a 20A RCBO and then use switched 1 gang sockets, or use a...
