kiwitrc: Speaking of things that make you sh!t yourself, the guy who mows our private road berm was telling me a good trick during a power outage.

He has a generator and figured out if you wire an extension cable with a plug at both ends then you can plug it into your house wiring when the power is off and run the whole house from the generator.

"Shiver"


I have a generator changeover switch for that.
Wouldn't that also power the other houses on his phase on his street?
The amount of 3x 10A Plugs to 1x 32A 3Phase socket with tied neutrals is unbelievable.


I wondered about that but I suspect that the newer smart meters might block it.

They wouldn't be able to stop the feed. They're just metering the power consumption. They're only smart in that they send the power usage back to base without needing a meter reader to look.

No one should ever do this to power their house, but if they did, turning off the main switch would stop the power running back up the street.

DON'T EVER DO THIS.


Probably a good idea to turn off the hot water heater, large appliances (bar heaters, jugs, largish heat pumps etc). Can probably leave the oven on (for the clock), just don't try and use it.

Actually, seems pretty pointless really.

Ok, so it's Wednesday. Has your electrician made this safe? I want, no demand, to see photos of the completed job, demonstrating for all here that it is safe now.

Hi nope not yet it's not connected still in it's box.  Electrician didn't turn up.
Interesting that these are available off the shelf with no literature, makes you wonder how many are incorrectly being used.

Speaking of it requiring to be in an enclosure, if it was going to be used as a portable bench supply, can it be put into a plastic enclosure with the terminals wired to a 3point plug?  Will ask the sparky this.

Any metal that is exposed outside the case would need to have an earth wire run to it. If there's none, then just the power supply needs earthing on the terminal strip.

There are rules about making sure that the cord is restrained and if the power supply unit doesn't have a mains fuse, your case will also need a fuse holder.
