Well, after running out of time and despite some great suggestions, I was not able to find a ready made nut so I broke down and made some. Besides here, I hit up my engineering co-workers and couldn't come up with something. Finally on the last day a

Scott, Now if he had only come up with the Excel spreadsheet so that we could just plug and chug! I know, I know, There's probably already an "App for That!" I have absolutely no use for that filter but it might be a fun way to try out th

Right now I'm working on a little project to run the GE relays off a PLC. It implements a few simple functions, like allowing the use maintained-contact switches (including photocontrols) or single pushbuttons in place of the system's standard doubl

I'm used to seeing a requirement for 2, AC feeds or battery backup sufficient to power the system for 24 hours in trouble and then 5 minutes in alarm. Many panels have 2, 12V, 7-1/2 AHr VRLA batteries in the bottom. Joe

As I understand it, through the research done during the development of CEE/Ufer systems, it was determined that conductors larger than #4CU had no verifiable effect on increased ability to clear fault current, so this would seem to indicate that in

I doubt 210.52(A) would apply to the laundry room but I still agree it is silly not to have any more receptacles in there. The others do seem to be violations if you can't reach a receptacle with a 6' cord, anywhere along a wall. It was either a guy
