    EICR item 4.6 Presence of Main Linked Switch. Is an RCD acceptable?

    Hi All, Does a BSEN61008 RCD fulfill the requirements of 537.1.4? There is no other means of isolation, the tails come from the meter straight to the single 100A 30mA RCD protecting all circuits via BSEN60898 MCB's in a TT installation.

    Acceptable readings for a NEW installation

    OK peeps I have just tested an 185 4 core SWA, and have got readings of 40 Megs on L2 to earth and L3 to earth. Although this is accepatable according to the regs, I feel it is unacceptable as a NEW installation, and indeed there is evidence of water on some of the switchgear, which clearly...

    Acceptable incoming voltage from substation to shop outlet

    Hi, I was wondering if anyone would know what the acceptable minimum and maximum on a single/three phase main incoming voltage should be. From what I have gathered you have a tolerance of +10 230V -6. Could you also quote from where it is mentioned in the wiring regs. Thanks.

    Just got back from a call-out, simple case of cooker taking the RCD out. A twin oven, seems in good working order so after a bit of a faff managed to get a clamp over the cpc at the switch (no idea where the house rod is!) and sure enough the bottom oven is leaking about 10mA when firing. So...

    Looked at a job today where the elderly occupants have the old rewirable fusebox tucked away high in a kitchen cupboard where neither of them can reach, or replace the fiddly fuse wire.
