General discussion • Re: Power multiple PI 5

You don't need to be either an electrical engineer or an electrician to attache a mains lead to the power supply I linked to with a screwdriver (it has screw terminals, put the wire in there, tighten the screw down, done). Same for the 5v wires from it to each of the Pis.

Plenty of 8 year olds doing just that around here in these forums.

I appreciate your passive aggression.

What aggression? Just speaking of how easy it is.

Please stop.

Remember that a lot of the world uses 230V (or thereabouts) mains, which is more dangerous than the USA 110V. Yes, it is easy to learn how to attach a mains cord, and we all had to start somewhere. But it is not a skill to learn alone. It is also not the whole story. All mains connections must be properly enclosed (see my early post).

When we are done with mains wiring, there is still the non-trivial problem of choosing suitable wire for the high current 5V connections, of fusing each Pi, and of making safe and effective connections. With 60A available, the potential for overheating and fire is very real.

Bottom line:

• If you know what you are doing, and it is legal where you live, that's fine.
• If you don't know, don't try to learn by yourself -- errors can be lethal.
• If it's not legal, get appropriate professional help, or take an alternative approach.
