Can ground wire be stranded?
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).
Can you downsize ground wire?
The answer is no if you’re looking for a simple answer. More complex answer – What everyone is trying to say in the comments is that you can size the wire according to Table 250.122 in the NEC. This table allows you to size the equipment grounding conductors according to the breaker size protecting the circuit.
What size wire do you run to a ground rod?
The NEC code specifies that a solid copper wire used to connect to a ground rod must be at least either #6 or #8 gauge (depending on the size of your electrical service cable). #6 cable cable will always satisfy the sizing requirement, though in some cases larger is desirable.
How thick does a ground rod need to be?
If they are listed, they need to be at least 1⁄2 inch (1.3 cm) wide and they will have a mark that says they are listed. If they are not listed, they need to be at least 5⁄8 inch (1.6 cm) wide. A listed ground rod will have a marking near the top of it that states that it is approved.
Can a home have 300 amp service?
Not many utility companies will do 300A services, some like Phoenix will allow a 320A service, but MOST will do a MINIMUM 400A 3-phase service. You should either call your utility company and ask for the high peak demand OR have a load study done on your existing service to determine if upsizing is really needed.
