I find it a strange how the NEC doesn’t seem to include mobile vehicles and trailers, like the OP has described, yet when it comes to mobile homes, 550.4,[A] also addresses mobile homes not intended as a dwelling unit and then goes on to list some examples of these other uses, like contractor (...)]]> Wed, 08 Feb 2012 20:55:15 MST Re: Conduit Bending Apps for iPhone -Master Bender http://www.electrical-contractor.net/forums/ubbthreads.php/topics/205278/Re_Conduit_Bending_Apps_for_iP.html#Post205278 Posted by KJay:
It looks very interesting, but I’m not sure if other than maybe when using stationary equipment and doing multi-shot bends, that I could see anyone having the actual need or time to use an app for most routine hand bending and offsets we do in the field. I can just imagine the look on the (...)]]> Wed, 08 Feb 2012 20:31:23 MST Re: Install manual pull fire alarm system http://www.electrical-contractor.net/forums/ubbthreads.php/topics/205275/Re_Install_manual_pull_fire_al.html#Post205275 Posted by JoeTestingEngr:
I'm used to seeing a requirement for 2, AC feeds or battery backup sufficient to power the system for 24 hours in trouble and then 5 minutes in alarm. Many panels have 2, 12V, 7-1/2 AHr VRLA batteries in the bottom.

Under circumstances where there could be a trip/safety issue, I would have no issue granting a variation for NO receptacle.

Yes they do and give less lumens at 120 volts which can be perfectly acceptable.
Obviously confirm the voltage is stable and within spec. When all else is good then cheep bulbs are not cheap if you have to change them often.

I have one of the GEs; the only markings on the connector are "AMP" and "85". It might be possible to find a mate in an electronics distributor catalog like Mouser or DigiKey. But it'sa n insulation-displacement (...)]]> Mon, 06 Feb 2012 09:26:39 MST Re: fire caulking penetrations after conduite run http://www.electrical-contractor.net/forums/ubbthreads.php/topics/205216/Re_fire_caulking_penetrations_.html#Post205216 Posted by twh:
