two heaters, one plug?

[psidriven]

I ran out of sockets on my relay box. is it safe to have two heaters on the plug and two powerheads on another plug using power strips?

What size are the heaters?

[psidriven]

300 and 250

[rimai]

You should be ok

thanks. what is a safe amp/volt limit for each outlet? probably do the same thing for my powerheads, though they probably use less juice than the heaters.

5 amps each outlet, but the box has 10A total capacity
