Any tricks or tips on making circuit map/list for old victorian type house, mostly K&T, some new kitchen circuits, but has three sub-panels that supply main areas of house, difficult to hunt and peck out circuits, anyone familiar with a Extech ct-40 tracer, it has 16 leads and common then test unit that will say which breaker lead at the recept.s? tried the walkie talkie route but too confusing with homeowner
I donít have any experience with the Extech CT40, but for the price, I donít think you could go wrong. Iíve had my eye on one of the Tasco CMT42S circuit mappers for a few years now, but that kind of price for something Iíve never used before just seems to always stop me cold.
Sometimes I will just shut off all but one circuit and do a walkthrough of the house with a receptacle tester and a notepad making notations as to what lights and receptacles are on that circuit. This is pretty time consuming for one person though, especially with a building like in the OPís case. Thatís one reason I would like to try out one of those circuit mappers next time this type of situation comes up.
I have one of those TestUm Lanscaper network cable mappers with 8-remotes and a bunch of different adapter cords, but I never actually thought about trying it on deenergized line voltage circuits before. I know if I unplug lamps and small appliances from the receptacles and turn off all the wall switches for ceiling lights, I can use a toner/probe to trace a deenergized circuit through the building this way, so maybe Iíll try the network mapper around my house and see how it works out.
I use to have a Paser tracer. ( I believe that was how it was spelled.) Then Amprobe bought them out. There were 2 types of tracers. 1 for live circuits and 1 for dead circuits. We used them all the time.
Iíve heard about the flasher trick for years, but have never actually tried it myself. I noticed that Cooper says their BP1008 flasher button has a 65-85 per minute flash rate. Is that something that would work with a digital amp clamp or is it better suited to an analog type clamp? My thinking is that it might be too fast for a digital clamp meter display to stabilize, but might be easier to see the needle bounce on an analog meter, although maybe not.
