Is there an NEC requirement that the neutral and ground buses be completely seperate? I looked at a house yesterday that had the neutrals and grounds for the branch circuits all run to the same bus bar.
Is this still being used for street lighting? Just curious about that.
You may consider looking at the transformers used for airport lighting. These are modern, constant current units that have similar outputs.
I wasn't sure what logo they were using these days. I also just knew it wasn't the hexagon I'm looking for. Probably a manufacutirng company in China is my best guess.
If you know the efficiency, you can take the rating 750 kW and divide by the efficiency, say .8 and get the power rating of 937 kW. Or find what the running current is. That will give you a much better answer.
I have the blade of a NEMA 5-15 plug and because of the fire, only the blade. It has a logo on it that is a hexagon with the letters ET inside it. Can any one identify the manufacturer of this?
Thanks
