210.23(A)(2) - 09/14/02 12:25 AM
A new home with 3 garage door openers(5 amps each)and 3 keyless lampholders wired to a single 20 amp circuit is a violation.
Correct?
Correct?

A garage door opener wouldn't be considered continuous load, so you could load a 20 amp breaker to 20 amps of non-continuous load. What is a keyless lampholder?

Keyless Lampholder, with a suicide tail!

Ron,
I don't believe continuous or intermittent enters into the consideration of 210.23(A)(2).

Redsy,
Sorry I didn't look at the article number you referenced before dribbling at the keys. Seems you have a valid concern.

What is your maximum wattage listed on the keyless fixtures?
Re: 210.23(A)(2) - 09/14/02 03:36 PM
Probably 100? I have seen 200 watt bulbs used in a lampholderthough!

Joe, the keyless fixtures we use are rated at 660W-250V. OUCH! We usually bulb them out at 100W.

(11) Other Outlets. Other outlets not covered in 220.3(B)(1) through (10) shall be computed based on 180 volt-amperes per outlet.
x3= 540W
Quote
(2) Utilization Equipment Fastened in Place. The total rating of utilization equipment fastened in place, other than luminaires (lighting fixtures), shall not exceed 50 percent of the branch-circuit ampere rating where lighting units, cord-and-plug-connected utilization equipment not fastened in place, or both, are also supplied.
5 A x 3= 15 A .....( you've already blown it, sorry...)

Minor program notes...
"Keyless" for these lampholders means "sans pull-chain switch."
A "suicide adapter" refers to one with the plainly visible green-wire tail that could readily contact the adapter's male ungrounded blade and "heat up" an otherwise floating [but intended to be grounded] appliance case. Nowadays, the connection is a rigid-metal forked tab. IIRC, either type of adapter has never been permitted in Canada…id est, if you have a u-ground cord cap, it must be plugged only into a u-ground receptacle. {Corrections gladly accepted.}

I think that if the lighting units weren't included on the circuit, there would be no violation.
Re: 210.23(A)(2) - 09/18/02 03:16 AM
It appears to be a violation, but...could someone explain to me how a door opener with a keyless lamp nearby is less "safe" than an opener with a built-in light?
Re: 210.23(A)(2) - 09/18/02 10:41 AM
John,
I guess the fact that the light on the unit is actually part of the "equipment fastened in place" distinguishes it from any other fixtures (sorry, luminaires) on the circuit.
