Q-Line® THQL2120GFT 20A Double Pole Circuit Breaker • 20 Amp Double Pole Ground Fault Breaker with Self-Test • 120/240 VAC 2-Pole GFCI Breaker • Ground Fault Circuit Interrupter

I knew these had to be tested before being resold, so I have high confidence they will work just like new ones would. So far so good…and this is for a metal out-building so no major concerns over fire safety since this isn’t an actual dwelling.

Easy to install

This will be the 3rd breaker I've had to replace in my pool filter panel in the last 9 years. The pool guy says that the Florida coastal air and heat tend to make the material porous as time goes on, causing the material to actually absorb moisture and cause failure. This one is made of the same material, but feels a but more solid. We will see!.

GFCI Trips under high load. At first I suspected the outlet, then a table saw, but when the GFCI kept tripping while using a plasma cutter I knew it was the circuit breaker. I am past the Amazon Return window, so have to eat cost of two of these. :-(

Replaced my 20 amp breaker for my early 2000’s Hotsprings Grandee that kept tripping randomly. Fixed my issue. My only complaint is that the throw lever has no amperage marking. I’ll solve that with a label

Delivery was timely ... product was exactly what was needed!!! Although its not rocket science to put a breaker in, if you're not an electrician, there are some things you need to know before making purchase ... - know the circuit breaker panel manufacturer to insure you get the right breaker - know and understand the different parts of the breaker and the panel - there are different types of breakers for each manufacturer ... make sure you have the right type of breaker that will fit on the bus

Easy to install.

Mine was defective! After wiring up, both poles were hot, but devices on the circuit didn't work. Took a measurement and the voltage between the poles was near zero. Somehow both poles were on the same leg of the circuit and essentially 0V instead of 240V. Then tested the GFCI and it just continued to make a clicking noise but not didn't trip. Packaging was strange too, in a cardboard box while others I have ordered were in plastic blister packs. Wouldn't trust this here.
