RT310 is an electrical tester that tests the wiring condition at an electrical outlet, and inspects and checks AFCI and GFCI devices. It is designed for use with North American 120V electrical outlets. It can detect and identify common wiring faults. Includes 3 x 1.5V AAA alkaline batteries.

• Warnings
• The tester is intended for indoor use only. Tester is designed for use with 120V AC electrical systems. DO NOT connect to higher voltage electrical supplies.
• Before each use, verify tester operation by testing on a known live and correctly wired receptacle and circuit
• Always consult a qualified electrician to resolve wiring problems.
• DO NOT use if the tester appears damaged in any way
• Read, understand, and follow all warnings and instructions before operating testers
• This tester only detects common wiring problems. DO NOT attempt electrical testing on an incorrectly wired outlet
