I think that in my area, it is hopeless to expect a proper earth 25 Ohm or less without significant expenditure.
The ground wire might share some current, but if the wire were to turn horizontal and not go straight down, I doubt the lighting's amperage will wholly follow it as it started from several miles up to begin with. A receptacle is a contact device installed at the outlet for the connection of an attachment plug.

A switch intended for isolating an electric circuitserving utility and the premises wiring. Fine print notes are informational only and are not enforceable as requirements of this Code. In lieu of the method provided in Column C, it shall be permissible to add the nameplate ratings of all household cooking appliances rated more than 1¾ kW but not more than 8¾ kW and multiply the sum by the demand factors specified in Column A or B for the given number of appliances.
An outlet where one or more receptacles arecircuit breakers, fuseholders, fused switches, buses, and watt-hour installed.

Aare connected and that forms part of the air distribution system. Our electrical engineer originally proposed a 125 amp panel box for our house.

Running the entrance cable in the attic The main feed cable has come into the attic through the weather head. The capacity of the circuit will be reduced. Please take time to read the many comments below. Where two or more single-phase dryers are supplied by a 3-phase, 4-wire feeder or service, the total load shall be calculated on the basis of twice the maximum number connected between any two phases. Since the panel box only came with a load and neutral buses, we added a ground earth bus. Typical single-family and multi-family dwelling units of different demand load are presented considering the single phase and three-phase service systems.
There are no electrical conduit tees. Mandatory rules of this Code are those that identify actions that are specifically required or prohibited and are characterized by the use of the terms shall or shall not.
