Here is an old 50's maybe Remote ballast can. This was found in the base of an abandoned light pole, the other two light poles already had everything missing but this one didn't, so I got it since the poles were abandoned and the parking lot had new lighting already.
It was originally powering an OV-20. I wonder if I can get the OV-20 that is still on the pole abandoned. There are some new Model 13's on newer poles but they left the old OV-20's up, There are three of them, one still has the refractor but it's a bit cracked, the other two are missing the refractors and lamps.
I wonder if I can save this one, The Arc Thrift store owns it and I have been working at one of those thrift stores for a while now... Maybe I can ask the store I got this from if I can have on of the OV-20's. The one this is from isn't the arc I have been working at, but it's the same thing and I have some connections with the store, maybe I can get lucky and get this OV-20 taken down for me. xD
I helped Ian with the wiring, it has 4 primary wires (H1 to H4) and two secondary wires (X1 and X2). Typical transformer set up. To operate on 120v you need to set the primary side in parallel by hooking H1 and H3 to hot and H2 and H4 to neutral. 240v operation is done by connecting lines H2 and H3 together and connecting H1 and H4 to the mains. Important, don't connect H1 and H2 together and same for H3 and H4 together, it will short out!
I've worked with 3kVA power transformers using the same exact configuration. I connected 3 of them on 3-phase power in different ways to get different voltages!
I hope my M-1000 is a 120 x 240, but unlikely since the other two M-1000's had 480 volt single tap ballasts. So it's likely my M-1000 with the original ballast is 480 volt single tap or 240 x 480.
I am glad this ballast can is 120 x 240 though, I will be able to light it! I still gotta test it first...
It seems tri-tap ballasts are pretty common in Canada though since CSA regulations require ballasts with a phase to phase input (like on 208, 240, 480, and 600v) to have a isolated secondary so only CWI ballasts can use those voltages here. Instead the 120/277/347V tri-tap ballast seems to be fairly common here.
I already tried and it tripped the circuit breaker. I am not sure why it tripped the circuit breaker but I am pretty sure that it was not wired for 240 volts.
