Rapidez de entrega, excelente presentacion y bien empacado

After a power surge form a blown transformer that took out our refrigerator, dryer, two security cameras, two window fans, an electrical outlet and a motion detected outdoor light, I felt a need to protect my electrical appliances in the event of another power surge. With a $1000 deductible insurance plan, it still cost me over $1000 out of pocket to replace everything. I installed this on the main busbar in the circuit panel, ahead of the circuit breakers. It was very easy to install if you know a little about electricity. If it works, it will be well worth the $100 spent instead of $1000 if another power surge occurs.

Easy to install but you need to buy the 30A breaker too so consider that in your purchase budgeting. Must have an electrician install it, or homeowner permit to do it yourself. This requires getting into your main power panel, so don't attempt if you are incompetent! Excellent product by world-class manufacturer.

Es exacto lo que necesitaba y mejor que un TVSS

Installed four for family over the holidays, this was the only one of the external units, since all but 2 breaker slots were occupied, and never throwing away the final 2 expansions! Installation was trivial, even bolted to the backplane bolts (see instructions for that detail). A 2 lug breaker/dummy isn't necessary, however, leave extra length for the 2 hot leads, and have someone experienced with working in panels made those 2 connections. Presuming you know how to connect ground and neutral safely in a circuit panel, you would later be able to power down the whole panel, cut the hot leads with enough excess length to wire nut the replacement unit's hot leads to the original wires when your initial suppressor has fried. You shouldn't need to clamp into the bus bars ever again. This needs to sit outside the panel, and the deepest 1/2" punch outs closest to the wall might not leave enough room for the box, we used a middle punch out. I used an extra threaded conduit nut on the inside and outside of the panel box so the surge suppressor case itself wasn't stressed. The green light is very reassuring that the panel is hot and surge suppression is active, but you might need a bit of electrical tape to cover if it is mounted in a bedroom or similar. If this can't be mounted directly to a panel because it is embedded in the wall, then order their recommended mounting kit, you won't regret it. (We were lucky and didn't need it.)
