I have a rather lengthy technical electronics question to submit for a patron. Please see below:
"How is a 277 volt lighting system wired in series to turn on a large group of fluorescent light fixtures wired in series? One switch turns on around 50 fixtures at once. I want to understand this from the breaker to the last fixture.
When changing out the ballast in a fixture, there are some wires that are not needed, that the electrician has removed and capped. This process is similar to a 120 volt system, but has more wires in the 277 volt system that (I think) remain hot.
I have tried to find the information by searching the internet, using the keywords Fulham Ballast Co. Inc. I also search the "How Things Work" web site."
Thanks for any help you can provide.
