    Hi everyone, I had a shaver socket installed inside a bathroom wall cabinet. It makes a constant humming noise that can be heard in the next room. Is this normal/faulty? Can anything be done apart from removing it?

    I'm charging a PHEV from a standard plug socket, and it works. However I purchased an extension and the standard plug going into the socket has melted... it got a bit too warm for a bit too long. Are there recommendations of specific plugs and cabling that could take 3kw comfortably for...

    G4 LED's & Aurora AU-LED16T 12v constant 16W LED Driver, does it matter about the polarity ?

    Using these lights (wired in parallel) 6 x 2W is ok to use a 12V constant voltage 16W led driver Aurora AU-LED16T. My question is they are a G4 fitting which goes, either way, does the polarity of the bulb cause an issue or do electronics inside take care of this. Many thanks in advance.

    Max circuit length for LEDs powered by constant current driver.

    Hi all. Constant current LED lighting is a new concept to me. Not that difficult to get the head around, but I cannot find an answer to the following question: How do I determine the maximum length of a ELV LED lighting circuit powered by a constant current driver? For a constant voltage ELV...

    Cable ratings - constant load?

    For argument sake, lets say a cable is rated at 100A clipped direct, ambient temp 30 deg. Does this mean it can take a constant load of 100A in those conditions or is the rating based on cyclic current? The reason I ask is on a recent install, following current cable guidelines we fitted a 35mm...

    Picked up a job where the previous electricians had not connected some collingwood LED stair lights (they were exited from the job!), they had been wired in parallel and no doubt hooked up to an LED driver, anyone up on their electronics? Have they definitely been fried or is it worth taking a...

    Fans and ohm's law

    I am hoping for some advice on powering a 12v computer fan from the mains. I'm not an electrician, just doing a humble diy project. The manufacturer states the fans actual input power is 1.6 W, with a maximum rated input current of 0.20 A. So, I believe I ideally need a current of 0.13A...
