Test your RV’s 125-volt outlets before plugging in with this easy circuit tester. Bulb-type indicators light up to show wiring faults in 3-prong receptacles, and five different light patterns reveal which fault is present—reversed polarity, open ground, missing neutral, or others. No leads to manage, just plug it in and read the bulbs. CETL listed for marine and RV use.
