the reason they say run 2 is simply in case 1 fails there's a backup.. and thats words directly from them.

The only thing bad about that idea is :
If one relay went bad how would you ever know??????

I dont know why they just dont sell /use a 70A relay like this

While I was working at the salvage yard, we had an ambulance come in. I dug around until I found the relay panel.

I know have about 60 - 50 amp relays and as many 50 amp breakers.

I have used them for all sorts of stuff over the last few years.
