I'm going to try to post a link to a pic of some ceiling mounted light sensors in a commercial building I'm working in. Two of these sensors connect by fiber to each flourescent fixture. I'd like to find out exactly what the function of these is, and if possible a brand name. Thanks in advance.

I have a commercial customer that ask me for a bid on cleaning the breaker panels & tightening all connections. ( no big deal). Then he gives me a copy of a letter his insurance Co. gave him.
It wants me to follow NFPA 70B standards. Any help would be helpful.
It's a small job (2 days work) I don't want to buy the NFPA 70B book. ]]> Commercial Electrical Forum CanElectric http://www.electriciantalk.com/f30/nfpa-70b-9826/ Grounded B Phase??? http://www.electriciantalk.com/f30/grounded-b-phase-9825/ Tue, 10 Nov 2009 01:54:39 GMT Just wondering if anyone has worked on a grounded B phase service!

I am writing a proposal to replace 230 existing "2x4" lay in style fixtures with F32T8 Econo-Flourescent in the same size and length as what is being removed.

What tax credits or other savings from the state of NJ and/ or the Feds can I show to my customers? This is the first time we will be doing anything so Green like this, so my father and I are rather green and looking for advice.

I'm looking for some lighting ideas for a "conference room" of a flower shop. This is in a basement, and I'll list some specs of the room. It is being re-done as follows:
  • BLACK painted ceilings.
  • light colored, hardwood floor
  • darker colored drapes lining the walls.
Basically, the fixture needs to be surface mounted, and look somewhat attractive. Right now the room has 2-Light 8 Foot fluorescents in it. Those need to go. The customer does not want to spend hundreds of dollars on a fixture either.

I was thinking something like this LaMar light.


Anyone have some suggestions for me?

Basically already told them that they're gonna lay off just about every guy they just brought on, so everybody is trying to out work each other.

Foreman said apprentices don't have anything to worry about at all. Later on, one of the new journeyman said to me that we're lucky that apprentices are in short supply right now. After he said that I realized that the electricians on this job, even before the mass hiring, outnumbered us by about 2-1, maybe even 3-1.

I'm not sure if this is just how the employer wanted to hire, or if what that journeyman said is true. I would figure apprentices would be easier to get a hold of than a good journeyman.
