Socket Tester with RCD and GFCI Test

Reversed polarity, a missing ground, and a GFCI that does not trip are three of the most common electrical findings in residential inspection, and all three are invisible until tested.

Plug this into an outlet and it tells you the wiring configuration immediately, then trips the GFCI on a button to confirm the protection actually works.

• Tests live, neutral, and ground wiring configuration
• GFCI and RCD trip test function
• Non-contact voltage detection built in
• Indicator lights with a printed legend on the body
• Plug variants for US, EU, and UK outlets

Test every accessible outlet, not a sample. Reversed polarity tends to appear where someone has done unpermitted work, which is rarely in the obvious room.
