Circuit Mapper Breaker Identification System - Now Up To 84 Circuits

• Determines which breakers are serving specific branch circuits in seconds
• Locates up to 84 branch circuits and requires only one operator (multiple operaters may work concurrently)
• Eliminates equipment downtime because circuits can be tested with or without power
• Identifies lines on any electrical wiring system 
• Circuit clamps accomodate wires up to #8
• Set includes clamps, accessories including a circuit map pad to write down each branch circuit

Full two-year warranty. Traditional methods of identifying circuit breakers and wiring are inefficient and expensive, often requiring two people to perform. With sensitive electronic equipment, simply turning breakers off and on is no longer a viable option. Even modern circuit tracers typically trace only one branch circuit at a time. The Circuit Mapper transmitter connects to lines at the panel rather than at the end of the branch circuit. The receiver displays the corresponding circuit number through digital signal processing, with or without direct electrical contact, so you know exactly which breaker is connected to each transmitter lead. There is no time wasted comparing signals or looking for the strongest signal. Using the Circuit Mapper system will greatly reduce man-hours spent when locating branch connections of electrical circuits...Multiple receivers can be ordered to greatly speed the mapping process and the efficiency of each job!

The Circuit Mapper can be used even on devices when plugged into an outlet (Perfect for computer rooms where power cannot be interrupted). The Circuit Mapper Receiver has a non-contact sensor at the base of the probe.  By aligning the the receiver perpendicular to the devices power cord (at the base of the receiver's probe) and pressing & holding the receiver's button, the receiver will display that outlets' circuit breaker.

Use on different power systems: If it is a 480V system with no neutral, that implies a 480V delta connection in which case there may or may not be one phase bonded to ground.  It means that there will be 480V potential phase to phase.  If it is 480V wye, then there is only 277V between neutral and each of the phases.
