    Spurious Voltage on 2 way switch??

    that is the "old" way and also called 2 plate or "conduit" wiring.. nowadays we use 3C+E and wire as shown in the picture.. it means that you don't have to get the switched live back from the other end of the run somehow and makes it easy to turn a 1 way switched light into a 2 way switched...

    Spurious Voltage on 2 way switch??

    I have devised a solution, but it involves converting the wiring to "2 plate" or "conduit" style wiring and the use of an intermediate switch at the "live" end with the need for a neutral at the "live" end..... ( could be done with an earth, but it would most likely upset an installation with an...

    Spurious Voltage on 2 way switch??

    what are you referencing your voltages to? is the earth connected in your lighting circuit? ( not all are.. ) the construction of 3C+E means that there is an earthed wire between 2 of the cores, but not between the last one and one of the others, it's usually this / these ones that have the...

    Picture where things are not entirely correct

    you mean the block next to the neutral that's linked to the neutral and has the green and yellow sticker on it indicating that it's actually intended as an earth block? :)

    Started My Diet...

    The following is not specifically aimed at you, more at the general argument.. On that basis, should the NHS pick up the tab for stitching you up after a drunken fall or brawl on a saturday night? after all it was your choice to get drunk... should they foot the bill for the oxygen tanks for...

    phase colours?

    We use 3C+E SY cable at work for wiring the fans to the inverters for large air-con units. They buy the stuff that's got 3 black cores with numbers on and we ID them at each end with U V W. They also make us put brown / grey sleeving on the relavent cores.. Now for the question.. Do you...

    Remote switching?

    does it need to be radio? you can probably do it with a PLC connected to a telephone with the right software in it.. you can buy remote power switches ready built for use in server racks etc where out of hours resets etc may be needed by the client / IT guys but these run into a couple of...

    electric v gas

    you could always fit solar panels to the entire roof and then the electric is even cheaper for you ( if you don't count the initial cost of the installation.. ) and use that electric to power a GSHP or ASHP.. you could use gas to power a gas turbine generator to provide your electric and the...

    new electrics need sleeving

    the edge of a plasterers trowl can be very sharp if it's much loved and used daily.. think about it, it's a thin piece of spring steel being rubbed repeatedly over an abrasive surface at almost the same angle every time.. it only takes one wrong hand movement and the trowel slides sideways...

    A few questions for a knowledgable electrician

    yup, you've been fobbed off.. I hope you reduced the amount you paid to compensate for the less than quoted for materials? ( ie if he quoted £X for the spec you asked for and put in cheaper stuff then you only pay for the cheaper stuff not the original quote.. ) I'd have stood my ground and...

    Conduit for earth & PIR

    yes but that sub main CPC is sized for the size of the sub main and not several sub mains in one location.. so even though a 95mm sub main serves several points, the CPC is sized correctly for that 95mm.. you don't have several 95mm sub mains with a single CPC..
