hmm. i wonder why they stuck cable ties onto slipfitter bracket...
joe_347V   [May 13, 2013 at 03:51 AM]
I'm guessing he stuck them in there as a strain relief for the cord. I did the same thing for my R47.

ahh good idea. Since i sometimes use my slipftters to mount the lights i can't do that.
joe_347V   [May 13, 2013 at 05:19 PM]
Yeah, there's might be something else you can tie the cord to though.

Eh it doesn't bother me with a terminal block. if the wires were wirenutted i'd be more concerned but with the terminal block there's less of a chance of something getting disconencted. I always inspect the electrical connections before i ever plug in one of my lights anyways. My OV-25 is an example of a light where the connections aren't made with a terminal block since there isn't one.

Mike,
I use cable ties on all of my lights as a strain relief like what joe_347v said. I just do it as a precaution just to be safe. I don't really use the slipfitters on any of my lights anyways.
streetlight98   [May 13, 2013 at 10:18 PM]
Yeah I might whip somehting up for my lights in the near future... BTW, would you mind showing this and the other two M-250r2s lit in one pic with the doors or lenses off to compare he brightness of the lamps? Cool

I see GE stopped bonding the neutral to the housing or did you remove it. I haven't changed a streetlight in months since I've been assigned to a major project.
streetlight98   [May 13, 2013 at 11:25 PM]
i thought bonding the nuetral to the housing stopped a long time ago? My M-400 split door didn't have the nuetral bonded to the housing. Come to think of it none of my fixtures do/did...

wow... it seems they don't even use ballast brackets anymore lol. all of my lights had used some sort of ballast bracket in them. these HPS reactors are small too!
joe_347V   [May 13, 2013 at 11:47 PM]
From what I know the Powerlites from the 90s also had the neutral bonded to the housing. They used the neutral from the secondary of the CWI ballast though.

It seems GE adopted the Powerlite ballast bracket less mount too, my R47 is like that too.
streetlight98   [May 14, 2013 at 12:59 AM]
yeah either GE was copying powerlite or powerlite was copying GE since their lumes seem to share some interesting similarities lol (slipfitter, also the B2255 and M-400/M-400A are essentially copies of each other lol.)
joe_347V   [May 14, 2013 at 01:57 AM]
Yeah, the PC sockets on the older GEs and Powerlites were also mounted using the same way. Also I'm willing to bet a Powerlite R7 is very similar in design to a M-250R2 too.

I installed 2 250 watt HPS PF-400's bAck in February for a substation and the neutral was bonded to the housing.
streetlight98   [May 15, 2013 at 12:47 AM]
i think it's an option if the ballast is CWI. on their PDF docs they list something like "CWI with grounded socket shell" if that is the same thing as bonding the nuetral to the housing thus grounding it? Neutral
