Ecm Industries Llc GCT-3304 Economy Continuity Tester

Product Description

The ECM INDUSTRIES LLC GCT-3304 is an economy-grade continuity tester designed to verify continuous conductivity across a wide range of circuit types. It is used by electricians, HVAC technicians, and other trade professionals to quickly identify open circuits, broken wires, or failed connections without the need for a full multimeter. The tester features a 36-inch insulated lead with an alligator clip end for hands-free probing, and a fully shielded indicator bulb that signals circuit continuity clearly. Powered by two AA batteries, it is a straightforward, reliable tool for field diagnostics.

The GCT-3304 suits residential and light commercial service work where fast go/no-go continuity checks are needed. It is well suited for low-voltage wiring checks, control circuit verification, switch and fuse testing, and general electrical troubleshooting. The carded packaging makes it convenient for counter sale or individual tool inventory. It is appropriate for use by licensed electricians, HVAC service techs, and plumbing or mechanical contractors who work with low-voltage control wiring.

Installation Notes

Always de-energize the circuit under test before using a continuity tester — this tool is not rated for use on live circuits. Attach the alligator clip to one end of the conductor and touch the probe tip to the other end to complete the test. Follow NEC guidelines for safe work practices when accessing electrical panels or control boards. Battery replacement requires two standard AA cells; verify polarity before reinstalling the battery cover.
