    Connecting a low voltage transformer using a external switch?

    Currently I have 4 small low voltage transformers connected to 4 circuits of low voltage yard lights. They are under my deck, and I turn then on and off using switches above the deck. I want to consolidate those transformers into one transformer...

    GFCI won't reset, small voltage neutral to ground

    I do general maintenance at a summer camp that includes a campground. One of our campsite electric posts is having a problem. The GFCI is tripped and will not reset. I tried a new GFCI outlet and same result. I'm also getting about 2.6v from neutral to ground, when measured at the outlet and at...

    Odd voltage on Off peak circuit

    While sorting out some issues with immersions at a flat yesterday, I ran into something that seemed peculiar (to me at least). Immersions need new thermostats/cut out, all quite normal.. However, while testing the lower (off peak) immersion I was getting 13V L-N - which I assumed was just my...

    UK Over voltage?

    Good afternoon, a colleague of mine has recently had three brand new Bosch washing machines pack up, each within four weeks of being installed. I did a check on the voltage and it's 246.3v. Surely this shouldn't have had an effect on the machines...? Bosch seem quite happy to keep replacing them...

    Electric Cooker 4mm Vs 6MM

    Hi there. I’m looking for some professional advice. I recently bought Beko Cooker model KDC653S, it doesn’t come with the electricity cable and according to the manual it require H05W-FG 3X4mm or equivalent with total power consumption of 10KW. I called all local shops including electricity...

    Voltage converter help (AU) to (US)

    Hi there, I recently bought a Worksharp mk2 knife sharpener. Got it shipped from the US so I need an adapter for it here in Aus. The sharpener is meant for 115v 60hz power supplies only. In Australia the voltage rating of most households is 230v 50hz I believe? I think I need some sort of step...

    Voltage measured when breaker is off

    Hi ther I'm fitting a new IKEA kitchen for my father and have insta Ed a new cooker switch. When testing with cooker breaker off I was sill seeing 9.6v on my multimeter. As I individually switched other breakers off I saw the voltage decrease witheach breaker till i switched off the main...

    The weirdest problem you have ever heard: slight input voltage increase seems to affect my pc performance drastically

    So for the longest time I had issues in this location while gaming. I am on a second pc build that exhibits the same weirdness that made me actually quit playing Fifa though I loved the game. To use a simple clear example of weird behaviour, a game like Rocket League (maybe some have heard of...

    Confused about voltage on machine

    Sorry this question may sound silly, but I really don't know anything about electricity so I'm just asking to make sure. So, recently I bought a machine from the U.S via Amazon. In the instructions of the Amazon page, it said to plug the machine into a 110V socket, but our countries run on a...

    Calculating broken PEN touch voltage with backup earth electrode

    My brain has been exercised a bit by this. Am I on the right lines with this extremely simplified example: If we take: -TNCS installation with a Ze of 0.2 ohms. -Plastic services, nothing bonded, keeping it simple -Line conductor resistance from supply transformer should be similar to PEFC and...

    what is the voltage? 180 volt? 220 volt - Myanmar

    If I turn off the breaker and measure the voltage across the breaker (upper and lower screws), the voltage is around 180 volt. If I measure the breaker's upper screw and the grounding bar of the breaker box, the voltage is 220. What is the actual voltage and why is the discrepancy? Thanks.

    Induced voltage in lighting

    Yesterday I had a call out to a 3 way switched top landing light which had a bayonet CFL bulb in it. Turn light off at either switch and lamp continued to flash every second or so. The wiring looked ok so I assumed (maybe too soon) an induced current issue but then a family issue meant I had to...

    Odd Voltage Dips In My Car

    I've had my car for about a year now and I've noticed when I drive that the voltage goings all over the place from around 13.5 then can dip down to 12.0 even into the 11. 's My A/C Condenser Fan has been burnt out and not working since I bought the car and I recently took it out and unplugged...

    Martindale V7 false positives?

    Hello All, I keep a Martindale VT7 voltage indicator in my kit bag as a rough an ready check for live then check for dead before I work on a circuit. Today I've had a situation where the VT7 indicates > 50 V on a light switch fascia plate (Schneider Lisse Deco) but when I check this with my...

    complex voltage drop question

    The project: Install 12VDC 3 Watt Low voltage LED pathway lights, one every 20', along a 420' boardwalk through a mangrove forest. There are 24 lights and to minimize taps in the main line they will be installed in groups of 3 with one light at the tap, one light 20 feet behind and one 20 feet...
