What is the minimum distance that an outlet (GFI protected, of course) can be away from a water source? Let us know if you have any more questions, or how it worked out.
#SERVICE WIRE FOR 100 AMP PANEL INSTALL#
You must sand off all the paint on your panel's sheet metal underneath where you will install the ground bus so you get good electrical contact between the bus and the sheet metal your "box" is made of. They are available in nearly all home centers for about $5 to $8. You will have to purchase and install a ground bus. It should be identified either with a label in the new panel, or in the installation instructions. This is a screw that passes through your neutral bus into the sheet metal of the new panel, effectively grounding the neutral, which is required in a main panel but forbidden in a sub-panel. This means that your "bonding screw" must be removed. Some electricians will advise you of what to correct and how, but some won't, and instead will want to charge you to correct your mistakes.Īnother thing to note: if you are setting up the new 100 amp panel, fed from your main panel, all neutrals and grounds must be separate in the new panel, as it is considered a "sub-panel". Once he does this he is responsible for the entire job even though he didn't do all of it himself.

Only note of caution is that if there is anything you do in your end of the work that is not code compliant, he will refuse to hook it up.

If you are planning to have a pro do the final terminations, what you are doing is called "roughing in". If you are using wire rated 75 or 90 degrees C, #2 is the right choice. (Black pipe is for gas & water, I think you meant conduit, either rigid galvanized, PVC, or "EMT".) Conduit may be run directly across the bottom of a joist legally, without a runner board. You are not permitted to run wire across the bottom of the joists without it, but the runner board method is legal. Staple your cable to the bottom of this board. This can be basically a 1 x 4 nailed to the bottom of the joists. If you go perpendicular across the bottom of joists, you must install a "runner board". Drill in the center (top-to-bottom) of the joist, as this is the point of least stress on the joist. It's thicker and stronger and protects your wiring from "physical damage".ĭrilling joists is OK. If conduit, schedule 40 PVC is fine below grade, but where you come up and it is exposed above grade, many inspectors require transition to schedule 80. You may use direct-buried cable but it must be specifically rated for direct burial. Minimum depth in residential, where the area is NOT exposed to vehicular traffic, is 18". Minimum burial depth under the most stringent cases, per NEC, is 30". It sounds like you're on the right track. I plan to use a pro to do the service panel hookups, but I'm justing trying to learn something here and do the meanal prep work. Hung from the floor joist (tight to the bottom of them ) say with a hanger Holes in each floor joists like the rest of my household runs ? Or could it be * whats the best / easiest way to run this stranded cable ? Do I need to drill ( other utilities will be going in there too ). It will then run outside into a trench that is now 42 in. thats to say the floor joists are easly accessable ( also in the crawl space ). The run will start at the main service box in the basement and then into a crawl space. I have W 2 AWG four strand underground cable for this 100 foot run. the new service box is a 100 amp unit with 20 breaker slots. The main service box has room for the 100 amp breaker I will add. The source will come from the house 200 amp service box. I am in the process of adding a new service box to a new pole barn.
