I came across this in a GE Panel today. The homes in this community originally had Heat Pumps but have converted to Gas. I saw the old a H/pump wiring in the attic and it was spliced in a box. When I opened the panel I saw this(pic) 14 gauge wire spliced to the aluminum heat pump wiring from attic(no ground). I have done several houses with this conversion and usually find the old wiring terminated in the attic and new wiring run to the panel. Beside there being no ground is there technically anything else I should mention. Thanks, Chris Hello Everyone... I came across this in a GE Panel today.

]]> Electrical crichiii http://www.nachi.org/forum/f19/heat-pump-wires-feeding-new-gas-furnace-45068/ Illumination of exterior door http://www.nachi.org/forum/f19/illumination-exterior-door-45061/ Thu, 12 Nov 2009 23:45:13 GMT I'll throw this out to the group.
I just inspected a house where the porch had been turned into a three season room. They added an exterior door therefore requiring illumination of the exterior door per NEC 210.7 (A)(2)(b). However there is a switch in the house (old main entrance and exit) that controls the two coach lights on the detached garage about 20 feet away. The detached garage does have a service door facing the exterior door in question so it requires illumination as well.
The question is : does the exterior door from the three season porch have to have its own light with a switch or does the garage illumination cover the requirement and if so, How far away can this light be? This is the third time I have run into this and have not gotten any good answers

The main service panel is outside at the meter. Wires into the main distribution panel from the "pool panel" are black, white, red, and green. Can I assume the green is the ground? and if so, it should not be on the neutral bass. Right?

At the reinspect the new panel was installed but I was told the AFCI won't work because of shared neutrals. I am not sure what the repair would be or can the AFCI's be installed anyway on the 3 remaining K & T circuits ?

I am not sure I understand the term "shared neutrals" appreciate your comments ]]> Electrical rperkerewicz http://www.nachi.org/forum/f19/arc-fault-knob-and-tube-45002/ Capacity http://www.nachi.org/forum/f19/capacity-44978/ Tue, 10 Nov 2009 14:22:48 GMT I feel I should know if this is a concern but........

My understanding is a GFCI will prevent elec shock in a 2 wire system. I have seen them in bathrooms and kitchens. The part that trips me up is, a 2 wire system is still not grounded. That should be a safety concern, but not unsafe with a GFCI installed. (correct?)
Second part of question, in a home with 2 wire outlets why couldn't a person put GFCIs in all the locations? Like the living room for example. I was ask this question the other day. The occupants would be protected, correct?
