Art 100: Branch Circuit, Individual: A branch circuit that supplies only one utilization.

Not to seem too harsh, but the Code is our living... if you're intimidated by it, you're only hurting yourself. In addition, as recent changes ('05 NEC) have finally explained, the Code is not intended to be the end-all list of electrical utilization equipment or methods.

One automatically needs to consider:

All 240VAC appliances, (that should be a no-brainer) like electric ovens and ranges, arc welders, electric dryers, air compressors, air conditioners, heat pumps, water heaters & electric furnaces

All 120VAC circuits folks wouldn't want tied into a general use circuit for safety or convenience, ie smoke detectors, dishwashers & sump pumps.

Suggest you invest in the NEC Handbook. It's pricey, but it's all the Code, explained pretty thoroughly, with excellent illustrations (I know 'cause I had no idea what they were referring to on some items [Linked Image] ).

We sell it here for $97.50 - cheaper than most on-line (retail $119)
