    Will this work? (For connecting 50 amp RV outlet to dryer)

    I'm a DIY'er helping a friend connect a 220v dryer to a 50 amp RV outlet. The dryer has a Nema 10-30R plug and is in a shed about 4 feet from the 50 amp outlet. I'm thinking about getting this cord to plug into the 50 amp outlet: https://www.amazon.com/dp/B08WM3NRT1 And connect that to...

    Upgrading service from 200 amp to 400 amp

    I don't have much room around my current 200 amp panel and want to upgrade to 400 amp. I'd have an electrician do the work but I am just trying to educate myself a bit before talking to one. There is not much room around the current panel/service entrance to put another panel. I have a 100 amp...

    Difference between FSU and 3 pin plug, both with 5 amp fuse for LED downlights?

    Is there an obvious reason why I can't just fit a plug onto my LED soffit downlights, fitted with a 5amp fuse and plug it into a socket rather than install a 5amp fsu? I'm fine with the plug being permanently plugged in as the socket gets no use anyhow. TIA

    Hello All, Just looking for a bit of advice on the diagram I have laid out for adding a 100 amp subpanel coming from my 200 amp main.

    Amp rating on spur - 2.5mm Cable

    Can I please check my understanding on the following. My ring is wired in 2.5mm T&E. It is on a 32 amp MCB and protected by an RCD. I am now contemplating a spur from one of the ring circuits to provide power to an electric hob. The Hob is 2.5KW which I believe, equates to 11 amps. If this is...

    When do amp ratings matter

    Got some amateurish questions. Please excuse me but want to set this straight in my head. Do amp ratings only matter when current is being drawn i.e. an appliance plugged in, light fitting, etc. To expand, if I have a 50amp MCB with a 1mm T&E cable going into a 5amp junction box, would that...

    20 amp breaker trips

    The 20 amp breaker that protects ceiling can lights trips with increasing regularity. It takes a few tries to get it to reset. The can lights (led bulbs installed 2 years ago) are on older dimmers. They worked fine until recently. Should I start by replacing the breakers, the dimmers, or...
