Had to step back

This is a 3 phase sub-panel feed with 3-wire MN cable through a steel conduit

We dont need no stinking neutral...or do we

Why is it so hot

If the bonding screw is in place, the conduit is helping. :roll:

If you look real close you can see that the loads have been precisely balanced to have no net neutral current for the panel.:grin:

Yeah, you can tell because the wire sizes are the same. ;^)

The time clock is used to balance the loads. By a precise and judicious cycling of phases a perfectly balanced load can be achieved. I've done it a million times.

There ya go. Now you just need to send in a patent for a wire-saving device. Catch phrase: "Tired of wasting money on all that neutral wire? We can reduce the size of your neutral by up to 100%".

They can file it right next to the var-load energy saving devices. :grin:

sorry...dint have any money left for a bonding screw
