The PoCo here is planning on running 4/0 triplex to feed streetlights off of a 100A DP breaker from the panel. Obviously, the first thing I thought was that 4/0 will not fit in a 100A SQD QO breaker although they can easily use Polaris fittings to reduce the wire size to fit.

What's got me is this just seems to be a poor design. I've never done street lighting or parking lot lighting and really do not want to so I guess I can't really make that assumption :rolleyes:.

This has got me thinking though; Is there anything in the NEC from preventing a 100A DP breaker from feeding however many streetlights are going to be installed? I've searched and searched and can't come up with anything. Seeing the earlier post at MikeHolts about parking lot lighting utilizing multiple 20A breakers got me thinking about this. ]]> Lighting Design chenley http://www.electriciantalk.com/f8/street-lighting-design-10058/ http://www.electriciantalk.com/f8/wallpack-light-9980/ Tue, 17 Nov 2009 02:31:35 GMT You have seen the before pictures on another thread with weight of the previous fixtures with covers pulling away from the box.

I am seeking objective criticism. The raceway was existing and UF wire sleeved through it.

The 6" HALO (H7ICAT) IC Air Tight cans are taller than the 4", requiring me to cut into the ceiling above the soffet. Unfortunately, the space above one of these lights is part of the return air for this room. The HALO IC cans are air tight, so is there any harm in placing them in this return air space? The junction box is also in this space (possible code issue). Moving the fixture is not an option in this case.

I could seal around the fixture with air duct sealant. This does not address the junction box issue.

Another option would be to block off that area in the duct with wood or metal to isolate the fixture completely.

Any suggestions? ]]> Lighting Design rmsowell http://www.electriciantalk.com/f8/recess-light-return-air-9873/ http://www.electriciantalk.com/f8/fixture-wattage-ratings-9828/ Tue, 10 Nov 2009 02:15:24 GMT If an incandescent fixture is rated for two 60w lamps, can a single 100w be installed instead?

Just looking for ideas to break up all the recessed, maybe I am thinking too much....

I know you can change to LED and that is nice but the flexibility with the MR 16 lamp choices are far superior. Anyway, it is Saturday and I am sure there are no Halo reps at the phones today.
