    Low Voltage track lighting fault

    Hi, could anybody please advise of any reason a Low Voltage track light, with 4 bulbs should only be working intermittently. This is controlled by a standard one way switch (not dimmer) and I'm assuming the fault is with the contacts for the bulbs. I was wondering if this could be a transformer...

    low voltage fan

    Hi All After fitting a low voltage fan to an existing lighting circuit, does a test have to be carried out on the whole circuit or just the extra part installed. Secondly does it have to be a eic or is a minor works acceptable as it is an addition to an existing circuit. Thanks all

    4in Low Voltage bathroom fan.

    I have checked the core cutter I have been issued and it has a 4.5inch core bit. The fan I am putting in is 4in (100mm) does it matter if its slightly bigger hole, as the fan square itself will still be big enough to hide this. Also trying to get my head around why I need to get a permanent...

    Low voltage tension wire lighting system

    Hi, anyone have any experince of these? I understand that a Type C breaker may be best? I've been asked to install a system of 5 x 50w on a 300va transformer witha run of approx 10m from the board to the transformer. Any recommendations on make, size & type of breaker etc? Regards

    Ohms Law and low voltage

    How come Ohms law doesn't apply when talking about low voltage downlights. i.e 50w divided by 12V = 4.16A so thats obviously wrong. I think Im getting a bit confused.
