AC Connection at Fused Disconnect [RE-wrenches]

[Allan Sindelar]

Mark,
It seems to me that this is the perfect situation for you to use John Wiles'
work. He has written that it is acceptable. He has published this as a lead
article in the September-October IAEI (International Association of
Electrical Inspectors, I think) journal. The article can be readily
downloaded as a .pdf file. He heads the Code revision panel for PV. If you
can't convince your local AHJ that it's legal with all this ammunition, you
must have forgotten the doughnuts.

Just to make it overkill, I'm sending you the .pdf article offlist. Anyone
else, it can be found via links at http://www.NMSU.Edu/~tdi.

Allan
