20A GFCI on 20A bathroom circuit

I'm looking to add a bathroom circuit to an old house bathroom that currently only has an outlet as part of the vanity fixture. The circuit will be 20A, and will feed a single duplex receptacle in the bathroom.

I have two questions:

1) Am I correct in understanding that if there is only one (GFCI) duplex outlet fed by this 20A circuit, the outlet is required to be 20A? Or is this only true for a single outlet, rather than a duplex?

2) Can the lights and vent fan in the room also pull off this circuit? I have heard multiple opinions about this, but nothing definitive.

Thanks!

So long as it is Duplex 15 amp GFCI is okay. As you wrote only if it was simplex would a 20 amp breaker be required.

Yes, so long as it supplies only one bathroom.

Picking up a radio station

R

Rick Johnston on Jan 17, 2015

I need some electrical advice from the brain trust. One of my customers has added a new building onto an older section. The facility is near the transmitting tower array of a very powerful AM radio station. The complaint is that the radio station is bleeding into the intercom portion of one of our systems. Our site visit showed that the radio station is also present in the telephones, on television speakers, and (quietly) in the overhead paging speakers. An inductance wand placed near any electrical outlets, light switches, or even some appliances reveals the radio station. I tried all the "normal" fixes to treat the symptoms -- grounding unused pairs in the mults, grounding shields at both ends, adding capacitors to the audio paths. Nothing helps. None of this happens in the older section of the facility, which is actually closer to the transmitters. It is also intermittent, and could be months between calls. It has been very cold lately (single digits) and the ground is frozen. I'm trying to see if there is a pattern of dry weather that coincides with past service calls, thinking that perhaps low humidity is reducing ground rod efficiency. In the meantime, any ideas are welcomed.Read More

Conduit may be rusted shut?

M

MiamiCuse on Feb 02, 2015

I have a 60s house where all the raceways are in EMT conduits, due to a flat roof, most of the runs are below, through a monolithic concrete slab about 4" thick. I am trying to add a 120V receptacle in the closet, where there is an existing junction box for the 240V water heater. I opened the junction box and saw two solid #12 conductors, thinking I should be able to pass two more #12 conductors through (one hot one neutral), I fish tried pushing a steel fish tape in, and no luck, about 4-5' in it's stuck. Now I am not that surprised, I usually don't have much luck pushing or pulling new conductors if the existing are sold conductors. So I was thinking, may be I will pull one of the conductors out first, then use the remaining one to pull 4 new stranded in. It was VERY difficult to pull one solid #12 out. Much harder than it should. Once I got it out I knew I am in trouble. Here is a picture of the conductor. [IMG]http://i173.photobucket.com/albums/w67/143house/Coontie3/IMAG2241_zpsng0zdske.jpg[/IMG] The entire run is only about 25', 5' down, 15' across, then 5' up to the panel. There is a long stretch I can see rust on the insulation. I am guessing the EMT conduit has corroded? After this I decided I should pull out the remaining solid conductor out. I don't think I could have used it to pull stranded, it was really difficult to pull it out, and it too has this rust all over. Then I tried my steel fish tape again, and again 5' in, no more. I am guessing that it is corroded to the point it will not even pass a steel fish tape? My thinking is I am out of luck and I need to be thinking of creating a new route between the panel and the hot water heater and abandon this run of EMT...or is there any way I can still find a way to pull 4 new stranded through? The rust feel dry, not wet.Read More
