For boat owners using shore power, knowing if electrical systems are safe and functional is crucial. The 30A/125V Hubbell Twist-LockĀ® Circuit Tester can quickly diagnose if power is present and if equipment is wired correctly. It's small and compact, making it perfect for use in dark, difficult to reach spaces.

The tester is modeled after the style and size of a standard Hubbell Twist-Lock plug. Its exclusive patented design eliminates the need for traditional measurement techniques and easily tests the condition of the circuit.

Users simply plug it into any 30A/125V locking receptacle, and the LED output back panel will instantaneously indicate the state of the circuit. The tester can identify seven improper wiring conditions, including an open ground or reverse polarity. Hubbell gives the user confidence that connections are made properly and in the appropriate position.

It arrives with an easy-to-read card to help interpret the LED signals. The Hubbell Circuit Tester is compact and durable, and effortlessly clips onto any standard tool belt. It is UL and C-UL listed.
