Thick tracks are current, not voltage related.

And by the way, I didn't see those images the first time around : I've got
all third-party (domain) content blocked by default.

How many low-voltage lines do you seee going to the relays at the underside
?   I see just a single one.   And that means the topside has the rest,
which I can't see.

And do remember there is a 30 Watts rating mentioned.  Which one should we
believe ?  That one, or the other, 2200 Watts one ?

I can guess a bit, but I'd rather not when letal voltages are in play. :-|
