AC polarity

Dear Jkubina, The black, AC hot wire goes to the narrow blade. There are neat test plugs available for testing. I believe Radio Shack and Hardware stores sell these. cordially, richard.....

Dear people: thanks for your help! BTW, I was NOT referring to channel polarity (phase) but proper house wiring to the AC receptacles, to minimize possibility of hum/noise.

Two comments about polarity: 1) polarity is important to maintain for TV transmission synchronization between the TV camera and the TV set. 2) many new electrical codes require that the outlets be installed "upside down", that is, the grounding plug is now on top. It was explained to me that under the old standard with the hot/ground plug slots on top, there was the (remote) possibility that if the plug was not pushed in all the way, it was possible for a metal object to fall down behind a dresser or a stand and end up shorting the hot/ground terminals. Point being, that the large slot is not always on the left! Happy Tunes!

Whose new electrical codes, I wonder? Sounds kind of silly. Maybe we should change the plumbing code to require that a shower head be placed no higher than 3 feet from the bottom of the tub because of the remote possibility that some fool will get hot water in his eyes upon entering the shower. Don't even get me started on those enviro-nazi low-flow toilets! ;-)

Here's an interesting twist. In my house, only the outlets that are controlled by a wall switch are mounted up side down so you know immediately which ones they are.

Abe, did you do that or was that done by some electrician that was actually thinking for a change ? If it was an electrician, we know it wasn't Glen that did it. HAHAHA Sean
