    (obscure) question about dual voltage in Canada

    Thanks very much for the reply. I wonder what the the transformer rating is and how many properties each one feeds...

    (obscure) question about dual voltage in Canada

    I was chatting to a non-technical person back over here for a visit but who now lives in Canada. He told me that the domestic voltage is 110v but some properties including his have a second feed of higher volts (unspecified but 200 and something Volts) for higher power domestic appliances. Does...

    Excessive??? Compact fluorescents failing.

    The leds are going to be a difficult sell on energy saving grounds alone, because the tl5cs are fairly efficient at 3300 lumens/40W but that said none of them apart from the new ones will be producing anything like that. Leds would however maintain their output for longer and be instant on...

    Advice after drilling through electrical cable above plug socket

    If I've understood this correctly you're saying the socket only has one cable in it, yet your holes were an inch apart and yet you drilled through the same cable twice? So you drilled one hole then drilled the next hole one inch above or below the first, or was the cable running horizontally?

    Voltage Present on Earth Line

    Apologies to the forum if I've posted inappropriately, I'll shall recalibrate my moral compass (or remove the magnets).

    Voltage Present on Earth Line

    It wasn't for my benefit and I don't do schadenfreude. There are three issues here, all which have been covered by other posters to this thread, you didn't safely isolate, you disconnected the earth and you don't appear to understand the difference between voltage and current. The top and...

    Curious box enclosing meter, with electronics

    There's green LED on lhs, does that flash at any particular rate linked to the meter rate?

    Voltage Present on Earth Line

    It's certainly not a Dvm "issue", A Dvm has input impedance as does an analogue vm. By asking that question it appears that you still have no appreciation of what you're actually measuring, and I suppose by inference.. (I'm too polite to finish that sentence).. It is however a "you performed a...

    Double socket spurred off of Ring.

    It's the middle of winter and minus 5 outside, your boiler breaks so off you go to find some 2.4kW heaters to keep your family warm. You have 2 , you borrow another 2 off a mate....

    Neutrals overheating

    Intriguing question if statistics prove it to be the case. Is it possible that the mechanical construction of some devices is asymmetrical, resulting in slightly higher heat dissipation the live side, so the neutral always gets just a bit hotter than the live, then over a period of time gets...

    13A switched Sockets with USB, Do the USB sockets work when switches are off?

    Thanks, looked at similar but was voted down.

    13A switched Sockets with USB, Do the USB sockets work when switches are off?

    I agree, the same philosophy should have been applied to recently replacing ceiling downlighters (not that I'm suggesting ceiling downlighters should ever have a usb port) but sadly the only way to cover the original huge holes made by an "enthusiastic" electrician who cut them an inch larger...

    That's very generous of you! Mine's a pint.

    13A switched Sockets with USB, Do the USB sockets work when switches are off?

    Thanks SC, I suspected they might be on all the time, I haven't looked at one yet, I assume there is no way to disconnect the USB part without disconnecting the socket? Bit of a pain really as the test wouldn't throw up insulation breakdown within the socket (unlikely now but who knows in 5...

    13A switched Sockets with USB, Do the USB sockets work when switches are off?

    Hi Are the USB sockets permanently powered irrespective of whether the switch is on? Anyone done any power measurements on one when nothing is plugged into the usb? Can they withstand insulation resistance tests? (if so up to what voltage?)
