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.

• Features
• Detects the most common wiring faults in standard, AFCI, and GFCI electrical outlets
• Test AFCI devices by simulating arc fault conditions
• Test GFCI devices by simulating ground fault conditions
• Capable of detecting a dual-open wiring fault with simultaneous open neutral and open ground wires (patent pending technology)
• Tester delivers clear visual indication of the wiring condition at the electrical outlet
• Designed to test North American-style grounded electrical outlets in 120V AC circuits (incorporates a three-pin plug)
• Electrical plug is on a 10-Inch (254 mm) flexible electrical cord to access electrical outlets in difficult to reach locations
• Low battery indicator and easily accessible battery compartment; Uses 3 x 1.5V AAA alkaline batteries (included)
• Powers off automatically after approximately 2 minutes of non-use to conserve battery life
• Built to withstand a 6.6-Foot (2 m) drop
• CATIII 135V safety rating
• Measurement category III is applicable to test and measuring circuits connected to the distribution part of the building’s low-voltage MAINS installation
• The RT310 features a patent pending AFCI test method that is unique to Klein Tools
• Tests AFCI and GFCI, Simulates Ground Fault and Arc Flash Conditions, Detects Dual-Open Wiring Fault
• GFCI Tester detects the most common wiring faults in standard, AFCI, and GFCI electrical outlets
• Electrical plug is on a 10-Inch (25.4 cm) flexible electrical cord to access electrical outlets in difficult to reach locations
• Warnings
• Read, understand, and follow all warnings and instructions before operating testers
• Before each use, verify tester operation by testing on a known live and correctly wired receptacle and circuit
• DO NOT use if the tester appears damaged in any way
• 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.
• This tester only detects common wiring problems. DO NOT attempt electrical testing on an incorrectly wired outlet
• Always consult a qualified electrician to resolve wiring problems.
