Well,
It is a remote power switcher, for mains rated appliances, the relays I have say 230VAC/30VDC @ 16A, of course, most AC stuff unless it's amplifiers or meaty power stuff will never get that far, I would rate a max of 10A but in reality it would probably be a few amps on the AC side, just worried about inrush current, which I'll have to investigate, each relay will switch one load (if someone wishes to put a power distribution block on it that's up to them!).
So i'm not switching anything specific it is a design I have been asked to look at for a friend who wants to build relay boards that are controlled by Micros such as a PIC, so I was thinking that 10mm would sound about right but rather than laying thick traces and risk it being wrong I could use some wire to link the power.
The relays have only small legs and are thin, so I wonder how they manage to withstand (even a 15/16A rated should support at least 10A continuous wont it?) such high current.
