General Tools and Instruments CA10 - Manual (Page 2)

INTRODUCTION
The CA10 is a special-purpose electrical tester designed to quickly identify and
locate single faults in low-voltage (120/240V) AC distribution lines (branch
circuits). It can also test the reliability and response time of GFCIs (ground fault
circuit interrupters) and RCDs (residual current devices) and check the wiring of
outlet sockets. The instrument’s ease of use, versatility and accuracy make it
the ideal electrician’s tool for preventing shocks, sparks, electrical fires,
equipment damage and poor equipment performance.
