    CU Change

    What out for borrowed neutrals on two way switching. It will trip both RCDs at once.

    CU change: incomplete CPCs in lighting circuits

    In answer to your question about R1 and R2 for lighting circuits with no CPCs, you will just have to put No earth in the box, but you could note down the line impeadance( L to N) if your meter can measure this. If the client does not want their ring circuit seperating, I would advise that the...

    Consumer Units in flats with 2 electrical feeds

    You could advise that the storage heater board be changed.

    2 showers in a property

    Not heard of an interlocker for showers before. You could use a contactor so that one shower is isolated if the other shower isolator is switched on. Might be easier (unless they've already bought the showers) to have two less powerful showers.

    Your Opinions Please..

    Not sure how deep the SWA will be from photos, but it must be at least 450mm below ground level and have marker tape 150mm above the cable.

    Cable Runs

    One solution is to fix a plank across the joists and clip the cable to it. That way you don't have to feed the cables through and you can comply with the maximum spacing for clips (OSG P.113) even if the joists are further apart.

    Continuity of protective conductors

    Is there a misprint in the Manual from Kewtech. On there website is says the KT 61 measures upto 200 MegOhms on insulation setting.

    2 RCDs same circuit

    The RCD side of things seems to have been answered. You shouldn't really have furniture in front of a CU, it should be easily accessible.

    Loosing work because of 17th changes

    There are quite a few situation's where an RCD spur can be used to fulfill the requirements for RCD protection. If for example a customer has a 3036 fuseboard and wants a outside socket, you could supply it through an RCD spur and just recommend on the cert that their fuseboard be upgraded.

    Earthing Yacht

    Just a thought, but fibreglass doesn't conduct electricity, therefore it can't be a conductive part and wouldn't need bonding.

    Garage job

    Another possible solution, if the customer won't agree to a consumer unit change, would be to split the meter tails after the meter and put a small (shower type) enclosure with a main switch and breaker to supply the garage seperate to the existing House RCD and consumer unit.

    help me out guys! theroy working out VA

    Seems a silly question. But have you checked that the back bell has it's donger correctly fitted. Cause if it dings then it theory it should dong, as the dong is done by springing back from dinging.

    switches in bathroom

    Only thought might be that a pull switch is potentially safer as it won't matter if they touch it with wet hands.

    Query regarding PME

    As described by Des, the neutral conductor in PME is spiked (connected to the ground) at multiple points on it's route to consumers, therefore you cannot get a shock off it in theory as it is at the same potential as you stood on the ground.

    Have i got a borrowed neutral

    Sounds a bit like someones made the fittings unswitched. How many wires at your light fittings? How many wires at your switch?

    Domestic smokes

    Personaly I put one light on the same breaker/RCBO as the smokes, so it gets noticed if it trips. That way if the smokes circuit needs to be worked on you only loose one light while it's off.

    parallel cables

    Don't know if you will get a cable big enough for such a long run. Would probably be best running two 100A Supplies depending on what you are supplying.

    Tripping out BOTH RCDs

    Only solution is to rewire the strapper in three core. Hope it's not a long run.

    zs results on tt system

    Seems very strange that Zs readings are so high. You might want to check the busbar has gone into the bottom of the RCDs properly. I've been caught out with thinking it was screwed in tight and got no power. The busbar had gone in front of the screw instead.

    rewire questions

    1) I've seen my old boss put henly blocks in so you can run both the old and new boards at the same time. That way you can connect up new circuits as you go. 2) and 4) already answered. 3) Cable rods (£10 in Proper Job for a set of 10 with hooks) can be very useful for feeding cable under...
