  1. You are correct. The elements are wired such that one comes on at a time. The Top first and then the bottom. And, of course, #10 copper is good for 30Amps.
  2. I always taught it like this. The Service transformer is just a 240 V AC transformer with a 120 v center tap. In our electrical world, current doesn't always try to flow to earth or ground, it tries to get back to it's source. Earth and ground and neutral is negligable in your scenario since you are referring to 240v. I can explain the 240 v potential but I think you are not ready for it. hehe
  3. I purchased his check list publication and loved it. Will try this as well....thanks!
  4. I don't want to start a firestorm but I am having trouble understanding the NEC's position on using jacketed NM cables in conduit. I can understand it being allowed for short distances for protection but what is a simple rule of thumb on this?
  5. Yep...that's the way I see it too, a few bucks and it's there. It just wasn't clear but the extension cord example makes sense. Thanks
  6. I understand the 6' rule around the room for receptacle spacing, but the 2' rule I have a question with. If I have a receptacle withing 6' already, do I have to place a receptacle on a 2.5' wall anyway. I have this situation. From the bedroom door I measure past a closet door to the next receptacle and it is 5.5' from the door. But because that closet is there, it creates a small wall greater than 2'. Just because it is greater than 2' doesn't mean I have to place a receptacle there does it? Hope this is clear....Lance
  7. Recently I toured a new home being built in my neighborhood and noticed a special caulking in all of the bored holes in the wall plates (up to the attic and down to the crawl space). Is this a new requirement by NEC or a local thing? Anyone familar with this?
  8. Good info guys....I appreciate the input.
  9. While reading Ray Mullin's 14th edition Res Wiring book (discovered him years ago as many of you have), I read that " The receptacle for the refridgerator in the kitchen is permitted to be supplied by a SEPARATE 15- or 20-ampere branch-circuit RATHER than connecting it to one of the 20-ampere SMALL APPLIANCE circuits." I understood that the small app circuits are reserved for the counter tops. In his house wiring example he shows circuit B16 as connected to Kitchen Receptacles, South COUNTERTOP, Refridgerator & Island. That looks like the Fridge & the Countertop are on the same circuit. What am I missing ? (Page 65 Section titled 'Countertops in Kitchens' & Page 66 second bullet point) Lance
  10. I was looking at the different codes for recptacles and I may be confusing that with "outlets" but here is my question. In one paragraph I read that a kitchen must have at least two 20 amp small appliance circuits and that they can also supply the receptacles in the dinning room. Then I read another paragraph that states these two small appliances branches can not supply other outlets. Help me out...can I supply receptacles in other rooms from these?
  11. Thanks Douglas, I've been reading this site for 2 months now and have really enjoyed it. Learning, yes but lots of laughs, too. Let me ask one more thing. If I decide to move this panel to an interior room like the laundry, I would have to mount a box with a disconnect at the entrance but do I run the wire in conduit to the panel ? I know it gets tricky but it should be do-able, right? Thanks..........
  12. I am in the planning stages of Building a new home and will be doing the electrical. I have not wired a house since 1996 and I have a question regarding the location of the circuit panel. The best location for the service entrance is next to the right hand garage 9' car door. I would like to place it just inside that door but it is only about 2.5' wide. I can not find location information in NEC 2002. Can you tell me if this location is feasable and or where I could find the info in NEC ? Tennessee may modify this but I am interested in the NEC's statement. Thanks
