Description

Testing GFCIs and afcis on a monthly basis is a good idea that is sometimes forgotten. Underwriters laboratories (UL) suggests that afci/GFCI Devices be tested every 30 days after installation to ensure they are properly working. Now the new self test & lockout feature enables the dual function circuit breaker to automatically and continuously test itself to ensure that it is working properly. If it is detected that the device has been compromised, the device trips itself and locks out the homeowner from resetting the device, reducing the possibility of the homeowner incorrectly assuming that the device was tripped to prevent a ground/arc fault. This effortless system guarantees that only the best protection is given to your home at all times.

  • Excellent quality gfci breaker!
Style: 20 Amp Pattern Name: Circuit Interrupter
I tried testing all my circuits before realizing that it had to be the gfci breaker that was worn out. I had not realized they did that after about 20 years. Mine lasted 30 years, so i guess it did well. Anyway, this fixed my problem immediately. Just for others' information, apparently these are supposed to be trip-tested roughly every month. I had not realized that either. Anyway, these work great and fully recommended. PS i had thought these were rather expensive until i cut mine apart to see what it contained. This contains a highly complex electronic arrangement of components. Having seen that, i can't really complain about the price. ... show more

  • Works as it should, but...
Style: 15 Amp Pattern Name: Circuit Interrupter
Replaces my second QF115A, first one lasted 5 years and second one lasted 7 years. Wasn't able to find one locally like last time. I think it's been replaced by an arc-fault ground-fault (AFCI/GFCI) unit but haven't yet determined which one.

  • Works
Style: 20 Amp Pattern Name: Circuit Interrupter
Bought this to meet code in a detached accessory structure. The way I did the wiring was not ideal for GFI outlets due to how it was branched, this breaker was more economical and frankly just easier.

  • Exactly what I needed and less than what stores charge
Style: 20 Amp Pattern Name: Circuit Interrupter
My circuit breaker main panel uses these and similar for the entire house. It's only 4 yesterday old, same with the garage door opener. Last week, the one for my garage door (it's one plug in the house) kept tripping when the temp would go over 100° F, after the 3rd reset in a row, I ran an extension cord to the door opener; guess what, it didn't trip that breaker for a week of days over 100°. Going to my local hardware stores, yes multiple stores, I was unable to find the Siemens QPF version and the salespeople were useless having no idea what I needed and not having this in stock. Not wanting to go with another brand like Murry or GE and risk it not fitting or worse, I decided to order this. It's the correct type per the instructions on the door of the breaker box, and fit perfectly. Just flipped the switch to off, checked to make sure there was no power, unscrewed the screws holding the two main wires, and the ground screw holding the long white wire that is part of this, then pulled the breaker out. New one fit in, cut the ground wire to length, connected it first, then put in the white and black wire and tightened them down. Flipped the breaker on, and plugged in the garage door opener. Has been two weeks without any issues. Plus this one is a lot less, around $20 less, than in the local stores. ... show more

  • Works as expected easy to install.
Style: 20 Amp Pattern Name: Circuit Interrupter
Siemens is a well known brand very reliable stuff great value for the money. Does exactly what it should. And if you know what your doing every easy to install and honestly if you don’t the directions are easy enough to follow. That being said if your not comfortable with this type of work I would suggest hiring someone it’s not forgiving if you make a mistake or are careless bad things can happen. ... show more
