    I'm looking at a break room in an office building with a refrigerator, microwave, and most importantly - electric range (residential grade). I've been asked to research the requirements for fire protection in this room. Does this room require a smoke detector or exhaust hood over the range...

    208V Single Phase Unbalanced Current

    This question has been bothering me for a while.. There are a lot of products on the market that can be connected using a 208V, single phase connection (two phases and one ground). Where does the unbalanced load go? If I connect this equipment to two phases of a 120/208V panel (120 degree...

    What is considered a high neutral current?

    Must be harmonics. Phase A: 145A Phase B: 143A Phase C: 158A Neutral Current = ?((Ia²+Ib²+Ic²)-(Ia*Ib)-(Ib*Ic)-(Ia*Ic)) = ?((145²+143²+158²)-(145*143)-(143*158)-(145*158)) = 14A This is all great input, thanks!

    What is considered a high neutral current?

    Current on the Neutral in the panel, correct. No neutral breaker :). The breaker is about 150A / phase loaded. I can see 33A on a neutral being an issue, but how much is too much?

    What is considered a high neutral current?

    Just curious. I was reading a load report that stated there was a high neutral current on a 200A Main Breaker in a 120/208V panel. The current on the breaker was 33.6 Amps. Is that considered too high? Thanks, -Mike
