    EICR - C2 for low voltage cable

    Hi, I have just had an EICR carried out and it has comeback with a few C2s. The only one I disagree with is the electrician raised as a C2 the fact that under the kitchen cabinets there are some LED strips with exposed single insulated cables. All these exposed cables are low voltage (24v)...

    Advice re voltage converter!

    Afternoon all! I was wondering if there were any electricians here who could share some knowledge please 🙏🏼. I have a Ninja dual zone air fryer that I want to take abroad. The country I’m taking it to is running on 110V, whereas the air fryer is 2470W. Would a voltage converter 110V to 220V-...

    Determination of Wire Voltage Rating

    I am curious about voltage ratings on wire. I'm interested in 10-4 for a 25-foot cord that will be carrying 25 Amps at 240 volts. There are two voltage ratings for this wire on Amazon, 300 and 600. Would it be prudent to choose the 600-volt wire since the peak voltage of 240 is 339 volts? Or is...

    Measuring Voltage Drop - With or without Load?

    I am sending power to some 5v led lights about 50ft from the transformer. I was going to use some CAT6 direct Burial cable that I kept after a contractor accidently cut it (I replaced the wire as I did not want to do an underground splice). So I plan to use 1.5 pairs (three conductors) for Pos...

    Low Voltage Dimmer Help

    I recently purchased these pathway lights: https://a.co/d/f08tuaE After installing them I realized they're too bright, so I installed one of these dimmers: https://a.co/d/3tf17Su The dimmer doesn't dim the lights very much. They go from extremely bright to very bright. They are on a 14v...

    Metal ceiling grid voltage

    100 volts on a metal ceiling grid when measuring from the Met to the ceiling grid Only when lighting circuit (led panels ) is on it goes away if the panels are disconnected from the drivers and left on Each panel has 25 volts from met to screws on the back they are class 2!! So the voltage...

    Load Balancing / Voltage stabilization

    Hello, I live in Mexico, where I have a small, un-official trailer park on my property. The property is serviced by my privately owned, 650amp transformer with two hot wires coming from the main lines on the highway. The transformer case is designed with a 3rd possible hot connection...

    240v outlet voltage drop under load

    I have a 3 prong 240v outlet for a dryer that reads 240v across both legs and 120 across the ground. When I turn the dryer on and have the multi meter to the ground and a hot leg it shows 120 but if I switch it to the b leg and ground it shows 40 then climbs up slowly to 120. The ground is new...

    High incoming supply voltage EV charger shutting down

    Hello, I have a EV charger that is reporting over voltage and is unable to charge. the charger will operate up to 253V The solar inverter reports voltages below 253V and when the solar is shutdown and isolated the incoming supply reports voltages in excess 248V consistently, peaking at 256V...

    Car radio battery wire zero voltage ! but original car radio is working when connected. Why?!

    Hi everyone I am new in this forum and this is my first thread. Car model: Toyota echo 2004 sedan. I used a multimeter to test the car radio battery wire ( blue/yellow) when it was disconnected from the car radio, its reading was 0v. ( as shown in photo 1 ) before and after ignition, isn't it...

    Why live to ground voltage is only 0V (in a 220V AC power outlet, there is also electric shock)?

    Hello, my name is Kelvin. I'm a trainee hydraulic engineer in Indonesia. I apologize if this question has been answered before / if this question is too basic. So we have a problem with electric shock coming from an electric panel. This panel runs on 220V AC supply & is used to run an inverter...

    Strange voltage on earth wire

    Hi, I've got a light with a ceiling rose in the kitchen. While rectifying some faults in the house I came across to the light and measure Neutral to live: 240 volts (which is fine ofc) however when measuring earth to live I'm getting 150 volts. I have checked for any touched wires with my Fluke...

    Super low mains voltage, what works?

    Some months ago the transformer feeding my road had a HV phase loss with the result that my house was only getting about 85V. It was interesting seeing what stuff worked and what didn't: for example, 60W bulbs glowed, fluorescent lights didn't(!), some LED lamps worked, others didn't, and my DAB...

    Voltage drop question

    I have a run of conduit 172ft from a 12x12 box which branches out to parking equipment with runs about 50ft from the box. My voltage drop calc requires me to run #10s to the 12x12 box. My question is from that box can I size down to the respected size of wire my machines need (#14awg) to branch...

    How can there be voltage on water pipes?

    Hi everyone, I need some help with an electrical issue I'm experiencing. I recently created a new circuit for an electric oven at my friend's place, and when I returned home, my friend called to say that the two water pipes connected to the boiler were smoking. When I arrived, I first measured...

    What is the incoming Voltage Before and After the Service Fuse?

    I know that after the Henley Block which houses the Service Mains fuse, the Voltage is 230v If we was to remove the fuse and Measure the incoming Live wire, would the Voltage still be 230v?
