Just added six naked light bulbs to the ceiling of my garage and the
improvement in visibility for working is so good that I want to add
For the six, I threw myself on the mercy of the guy in the Home Depot
electrical aisle: #14 Romex between bulbs.
But when I got home, I realized that the porcelain fixtures used for the
bulbs do not have a ground connection, so the ground wire in the Romex
3 bulbs, 25 watts each... seems like I could just use lamp cord...
Or is there a fallacy in that reasoning?
Lamp cord will carry the load, but the size of the wire depends on the
breaker. 15A breaker requires #14 and a 20A requires #12
If the boxes are metal, the ground keeps the metal from becoming
You mean I need to scrap all my lamp cords
and put #14 wire on my desk lamp, shaver,
and table top radio?
(OP can put in a power socket, and run the
lamps off lamp cord and a plug. Make the
lamps look temporary.)
It might be a violation , but it works as *temporary* lighting . Right now
there are 3 porcelain fixtures on the ceiling of our new room that are wired
with zip cord . I wired them into the switch box to make it easy on the wife
, she doesn't like fumbling with an extension cord in the dark . Neither do
Wire receptacle to switch, and plug in "temporary" lighting with lamp
cords. Then you are legal - as long as the lights are mounted in a
"temporary" fashion - like hung from hooks, not screwed to the

Years ago, I was talking to a counter man at
an electrical supply house. He told me of one
customer, ordering large amounts of lamp cord.
Finally the counter man asked if he was doing
appliance repair. No, the customer said he was
rewiring his house, and that Romex stuff was too
hard to get through the walls.
Real story, told to me. Maybe twenty or so years
ago. People now days, not much smarter.
I;ve seen it. Back in the 60's and 70's I did some sideline window and
door work. Some of my business was in new house developments. Many
finished the basements and I've seen some strange things.. Lampcord was
one of them.
Looking to buy our house I looked at quite a few. Found one - very
nice, basement nicely finished - until I looked in the adjacent room
and found the basement was wired with old outdoor telephone wire -
like solid steel twinleed. - no ground. Happens the seller was a
retired Bell guy.
*For permanent wiring attached to a building you must use an approved wiring
method such as Romex, BX, MC or conduit. That includes installing the
proper size electrical boxes with approved fittings and grounding all metal.
Lamp cord is not rated for a permanent installation. In a garage where the
temperature and humidity is not fairly constant the cord insulation will
eventually dry out and become brittle. Using lamp cord in this manner is
just asking for trouble.
How about posting a picture of this job?
*It looks as though you used metal octagon boxes with the light sockets
attached. The metal boxes need to be grounded. There is a 10/32 tapped
hole in the back of the box for this. It also looks as though you ran the
Romex through the knockouts without a connector. You could have used a
button or a Romex connector.
I would have just installed a couple of 8' pans with 4' T8 lamps. Less wire
on the ceiling and more even illumination. Also you would have a little bit
more head room.
