225.33 Maximum Number of Disconnects.
(B) Single-Pole Units. Two or three single-pole switches or breakers capable of individual operation shall be permitted on multiwire circuits, one pole for each ungrounded conductor, as one multipole disconnect, provided they are equipped with identified handle ties or a master handle to disconnect all ungrounded conductors with no more than six operations of the hand.
I had an electrical inspection yesterday and didn't really know what to say. This is the first time I have actually ran into this.
Most service panels have disconnects. The panel yesterday did not. There were approximately 12 breakers. Three of them were pinned together (240 volt).
What exactly is SIX OPERATIONS OF THE HAND? If I can lay my hand up against five breakers and turn them off, is that one operation of the hand? That would mean I could have 30 breakers without a main disconnect!
