Re: Cabinet

The outside diameter of the cord means almost nothing.  Check the label!!
Thick insulation, or paper costs a lot less than copper and the inexpensive
extension cords are mostly that.  You want 14 AWG or 12 AWG flexible cords.
Costs a bit more, but works a LOT better and, because the budget is higher,
the cordage itself is usually more durable.
