Is All 10 3 Wire the Same?
I am going to install an inlet for my emergency generator. The wiring from the inlet to the transfer switch will be 10 3 with ground, 30 amp. At Lowe's they sell a 50 foot roll (somewhat more than I need) for $106.00. It's flat and looks like the rest of the wiring in the house. Across the street at a local place they also sell 10 3 with ground, but it's round, like an extension cord. They sell it by the foot, and I would only need about $60 worth. Is there a difference between the two that I should be aware of? Thanks in advance.
