im sure that it won't run for 3 hours or more, but who knows...im sure im supposed to consider this a continuous load
Doesn't the name plate already have 125% figured in?

yes, this unit has a 30 and a 60 on it already...it has a bonding strap if you choose to run one feeder or you can remove it to use two wires

There is nothing wrong with this instalation. You can put #6 romex on a 60a and #10 on a 30a breaker all day long. I would do it this way if I already had the wire.
why ?????????????????put #6 romex on a 60 amp breaker with a load over 55 amps and you will get a red tag in this area.
put #6 Romex on a 60 amp breaker with a load over 55 amps and you will get a red tag in this area.

And it should get a red tag :smile:
because of it's 55 amp ampacity

They don't make a 55a breaker check 240.6
You can go to the next standard size.
Got a code number ? Or this just what the boys want there ?
You can not use 240.4 to bump up to a 60A breaker if the calculated load exceeds the 55A that the wire is good for. This comment is from NEC Plus website commentary to 240.4:
" For circuits rated 600 volts and under, the allowable ampacity of branch circuit, feeder, or service conductors always has to be capable of supplying the calculated load in accordance with the requirements of 210.19(A)(1), 215.2(A)(1), and 230.42(A).
Read Augie's post again in it's entirety.

We are talking about 10KW heat strips right? and not any other loads.
