Installed easily, just hope it does what all the hype claims.

I installed numerous (200A panel) copies of the earlier model of the QO plug-on neutral GFCI/AFCI breaker, and had endless problems with nuisance AFCI trips on various circuits - LED lighting, washing machine, kitchen microwave, etc. Ferrite cores, surge suppressors, etc. shouldn't be required to make a circuit breaker function correctly! Siemens should never have marketed those breakers until they had done more development and testing of the AFCI portion of the breaker to better-characterize load profiles to distinguish "true" arc faults from everyday inductive loads.Good news is - these newer-model breakers eliminated ALL of the nuisance-trip issues in my house. Strongly recommended for use in replacing those pesky 2017-2018 (everything up to when this model was released) breakers that have nuisance-trip issues.

Very easy to install and it has a pilot light to indicate you home is beign protected.

I was upgrading the electrical panel in my home to a 200 amp service. I always wanted to have a whole home surge protector. Don't try this project unless you know what you're doing!!!!!!! And open electrical panel can be deadly. Installed easily and seems to be working just fine.

Have to cut off plastic nipple in order for it to clip into service box. Beside that it as an easy installation.

Turn off power at the main. This one snaps into place and requires no wiring. I did have to move some breakers in order for the device to be located nearest to service lines. Otherwise install was simple. Read & follow the instructions or hire a professional.

Easy to install once you remove the black tab, no wiring needed just popped right in! So Easy Electrican didn't even change me anything 🙃
