Cooper OVF
|
Found this brand new in box Cooper OVF at Restore today. It's a fairly common light used for new installs in Ontario. This one is 400w HPS and sports a tri-tap ballast that's huge. It didn't come with a lamp or PC so I stuck a new Sylvania 400w HPS and used a GE shorting cap I got from Mike to light it up.
Note the cardboard looking thing in the top left pic, it's a ballast shield that's common in a lot of Canadian cobraheads. My R47 also had one but it was cut away.

Stopped in a ReStore today myself .. as with the past couple times I went there, I left with the same amount of stuff I went in with .. nothing.
The re-stores here are less impressive now, they have way less stuff, I think they get rid of the cool stuff now because they didn't sell well or something.
One more thing why is there no 277V tap? Does Canada not have 277V available? In the US bigger buildings usually have 120/208/480 Available but I have never seen a building with 347V in the US
347V is only in Canada. The Canadian electric code doesn't allow phase-to-phase ballasts without an isolated secondary so a special ballast is required for voltages like 208 or 240V. There were some 150W HPS GE post tops for sale at a ReStore along I-395 near US 6.
Yeah I heard of 277v being used here but it must be really rare and I suspect it's only used to run imported American equipment since 347v is used instead for the most part. The tri-tap ballasts are very common here instead of multi-tap ballasts for the code reasons the Mike stated. All ballasts on a phase to phase circuit are CWI type which is more expensive and more lossy than a CWA so those voltages are rarely used to run HID lighting.
