Mell Should ground wire be solid or stranded?
Outside, aluminum or copper-clad aluminum cannot be within 18 inches of the earth. The grounding conductor can be bare or insulated, stranded or solid, and must be securely fastened in place and run in a straight line from the discharge unit to the grounding electrode (Photo 2).
What size of ground wire is needed for 200 amp service?
| GROUNDING ELECTRODE CONDUCTOR SIZING (Table 250.66) | ||
|---|---|---|
| Size of Main Panel | Copper Conductors | Aluminum or Copper-Clad Aluminum |
| 125 Amps | #8 AWG | #6 AWG |
| 150 Amps | #6 AWG | #4 AWG |
| 200 Amps | #4 AWG | #2 AWG |
What size ground wire do I need for 200 amp service?
GROUNDING ELECTRODE CONDUCTOR SIZING (Table 250.66) Moreover, what size wire do I need for 200 amp service? So, for a 200-amp service, you would still be allowed to choose a 4/0 AWG aluminum or 2/0 AWG copper, but you would choose it from the 75 degree C column in Table 310.15 (B) (16).
Can a ground wire be solid or stranded?
Everyone who has electrical service has a GEC. The GEC is the wire that runs from your Meter Can aka Service Disconnect Device, straight down the wall going to the rod beneath that is part of the Ground Electrode System. It can be either solid or stranded.
What is the minimum size grounding conductor?
GROUNDING ELECTRODE CONDUCTOR SIZING (Table 250.66) Size of Main Panel Copper Conductors Aluminum or Copper-Clad Aluminum 125 Amps #8 AWG #6 AWG 150 Amps #6 AWG #4 AWG 200 Amps #4 AWG #2 AWG
Can a 6 AWG ground wire be stranded?
For that you can use anything you want, only requirement is make it at least a 6 AWG or larger, and there is nothing gained making it larger as it does not change the impedance. It is only there for safety and zero-volt reference. It can be stranded, solid, insulated, bare, tinned or not tinned.
