Is there a resource to find the above on the net or even in a catalog?

We have a large electric grill that was badly underwired. It is 3 phase 208 with 4 elements. It pulls 37 amps with #10 wire on a 30 amp breaker. The breaker does not trip. I noticed that it warms up within 10 minutes then the tstat cycles the elements and the current goes from 12 to 25 depending on how many elements are running. In fact they all turn off after 20 minutes or so.

Just to add to the story, theres two feeds to the grill both 3 phase, instead of using 2 - 3 phase breakers, they used 3 - 2 phase breakers. Parts are ordered to fix that.

The reason this whole thing came to my attention was that it did not work right, one phase had low voltage, turns out that the feed is run through a contacter to shut it down during a fire alarm. One of the contactors contacts had melted due to a bad connection.

The breaker is a GE TEB if that means anything.
