Review on π Enhancing Electrical Safety with Siemens QF120A Ground Circuit Interrupter by Jon Delgado
It is easy to install on the panel, but it needs a little experience to do it safely.
For years I've been plagued by an external GFI connector mated to three connectors that keep popping up due to inexplicable GFI malfunctions. I could never find a fault with the wiring or the actual connectors. I ended up removing the GFI connector and installing this GFI switch on the main panel instead. It's been two months now and no more problems!
Pros
- Enjoyable
Cons
- Not as thick as other picks
