I got out of the Air Force knowing LOTS about electricity; repairing and maintaining racks of tube and newly transistorized equipment.
After four years and a marriage and buying an old house, I was ready to tackle problems.
The first was installing a garbage disposal in the kitchen sink.
I knew that Black was GROUND and thus White must be the power.
.................
It was a shocking experience to find that houses and 'tronics are; shall we say; a wee bit different!
What I'm doing now, wiring this old shed for power, is pretty straight forward. Several light fixtures, several outlets wired to an existing breaker box. 12-2 NM cable, 15 amp outlets, simple porcelain light fixtures. Should be a piece of cake.
The proof in whether I wired it right or not, will come when I flip the breaker back on. It'll either work or will fry. Here's to keeping my fingers crossed. :-)
