    three phase coolant pump

    You can get away with it with a small dual voltage motor connected in delta, giving 230 to each winding, but that motor will only be getting 115- 120v per winding connected in star.

    three phase coolant pump

    Looks like he's connected a capacitor across the terminals to create a phantom 3rd phase , usually the motor must be connected in delta but that doesn't look like a dual voltage motor so I would say that's the problem the motor will be running a lot slower than it usually does. Winding street...

    Filling out EIC tick sheet

    The rcd protects the modified part of the circuit from the rcd spur point to the flex outlet in the bathroom, so this is correct?

    Filling out EIC tick sheet

    Yes it's a panel heater, the rcd spur was installed next to socket and and heater supplied from this, but what you are saying the whole existing circuit must be brought up to current regs.

    Filling out EIC tick sheet

    So the rcd supplying the modified part of the circuit is not sufficient it needs to be at source? Who said anything about avoiding regs.

    Filling out EIC tick sheet

    Ok so in this example the BS3036 would be entered on the MWC Would a note be made that the existing circuit is not rcd protected?

    Here's another one, when filling out a minor works for the addition of a panel heater spurred off a socket, socket supplied with rewirable fuse, RCD spur point then through the wall to and flex outlet, is the overcurrent device for the modified circuit the 1362 fuse or the rewiriable fuse...

    Any tips on lifting glued down chipboard?

    We just use a circular saw set to the depth of the weyroc, cut back to joists and fillet the sides and replace with new, glued and screwed back down to stop any squeaks, usually only need a sheet up in the middle of the room above and fish to each hole with rods, if we come across a joist we...

    Filling out EIC tick sheet

    Query when filling out EIC for an additional circuit, When filling out an EIC for additional circuit, Is the tick sheet applicable to that circuit only or is is talking about the installation as a whole? For example where it states Cables correctly supported throughout their run obviously this...

    Fault on underground Sub Mains cable

    Rough calc volt drop would be about 20v for 120mm For that length at 300amp using x value

    Fault on underground Sub Mains cable

    120mm direct in ground seems a bit small for 300amps let alone the 530M run?
