Hi All
I am new on here and looking for some advice on converting a car ramp to single phase. This particular ramp is sold in 2 versions single or 3 phase. I bought a 2nd hand 3 phase version at very handy money so can justify a bit of spend on it.
The 3 phase version i have has a 2.6KW 4 pole...
Just sat contemplating life and realised i don't think i've ever seen any RCD protection on the boards we maintain/install at work.
I've seen 300mA protection on some section boards but don't recall ever clocking a 30mA in a 3 phase board.
Am i just not looking properly?

I thought it was a domestic house but it was a B@B. It has a 3 phase supply. I always pass on commercial or 3 phase as it is outside of my remit. However, I am toying with the idea of fitting this EVCP IF I can fit it from a single phase...
Hi there thanks for helping if you do, but was wondering on testing r1+r2 on a 3 phase distribution board could I link out L1,L2,L3 to earth and there for take all my reading that way ?
I've been watching Residual Current on youtube (great vids and great bloke btw) and really love watching the more industrial/commercial side of things.
Are there any resources that teach how 3 phase works? Even college syllabuses seem to be very light on 3 phase stuff.
How do people learn this...
Hello everyone, I really hope this isn't an idiot question but boy, I'm out of my depth! I've spent about 3 weeks (not solid mind) trying to work out how to size a generator to power a lathe for a test.
Situation is, I'm buying a house in Wales (UK) with a restored lathe in it. It's 3 phase...
