Unless hidden splitters are grounded you will find the tone on all cables connected to a splitter.įinally if nothing else works connect one cable at a time to a signal (cable TV or antenna) and take a small TV around and see where the signal appears. If no beer then continue by toning between shield and building ground. If you can map all the runs this way have a BEER! This will allow you to find all the continuous runs as tone does not always penetrate hidden splitters. Start toning from the building entrance using the center conductor and shield. Then I document where everything is connected before disconnecting everything. I usually start with a hand drawn floorplan showing all the places where coax appears. The common practice of having splitters all over the place causes many problems. Unless the all the cables are disconnected toning can be very difficult. Connecting a toner between a grounded shield and building ground results in little if any tone anywhere. In a properly connected system the shields are connected to building ground at the entrance. Components – Coils, Heaters, Motors, etc."how about one clip of the tone to the cable shield and one to a bldg ground ?".Accessories – Humidifiers, Air Cleaners, HRUs, Fans, Filters, etc.HVACR Equipment, Components & Accessories.Electrical Theory, Circuits and Electronics.Klein and others make a RJ45 -> alligator clips to use the toner.

Step Inside.Quick Navigation Tools & Test Equipment Top One of these days ill make a better one with a gfci breaker. I've only had to use it hand full of times over the last 4 years though. Things held up great considering the wire terminals weren't meant for solid wire. I made a power thief with bigger cheap alligator clips and some 12/2. Smoked both jumpers but I got er done.Did you pull the wires on your end and put another pipe inside or free hand it? lol and then milked the saw till I got the conduit cut. I used two alligator clips and clipped the plug terminals of the sawzall cord to the clips and then hooked to leg of 208 and ground. this was conduit with wire in it so I couldnt take it down. didnt have batt ree sawzalls then and there was no way I was finding a place to run a cord. I was on a roof one time years ago and had to cut a piece of conduit off. they looked a lot better than the other brands I see at the supply houses. I saw some bramec brand clips at a supply house the other day. If you have any problems with the registration process or your account login, please contact support.
