100A Generator Transfer Switch,24000W General-Duty Double-Throw Safety Switch,120/240-Volt Transfer Switches,Stronger Stability Manual Transfer Switches,NEMA 3R Standards for Outdoor and Indoor

Simple and effective but even better was the price

Well Built, using for a dual generator setup. Indoor/battery and outdoor gas/propane 240v inlets. I will say that I did look through some of the reviews and photos. With that said, I cannot give electrical advice to the masses, but you should know what you're doing. I saw some people claiming that they're using this as a home backup switch for their generators, and yet on the terminal block for this transfer switch, they have both neutral wires and ground wires going to that same bar, which means they are bonding within this switch. For a portable generator set up, you should not be doing that the only place that you should be bonding or connecting the neutrals and grounds is in your main panel. Additionally, minor things like, making sure the sheathing of cable extends into the box appropriately, etc are code violations in all US locations under the NEC. Local codes tend to be more stringent. However, this is about the switch and it is well built.

Had a difficult time finding a transfer switch during storm. Was excited when I found this one on Amazon for less than any others. Have already used it twice and works well and easy to install.

Exactly what I expected

Very good

This worked like a charm to transform a sub panel into emergency panel for generator. A few things to consider are there is no separate bonding/grounding Bar included. Only a neutral with bonding screw is included. Also, you may want to purchase reducing washers for your connectors because the pre-punch knockout break out too large if you’re not extremely careful

Works well and have had no issues with it .

Works great good value

I would never install 100 amps to this transfer switch even though it's rated at 100 amps. The max I will put through this switch is 50 amps. It's missing a grounding lug and it doesn't have spring release when switching which reduces arcing on contacts when a load is connected. Need to add a grounding lug and switch under no load to be safe. The box is made of sturdy metal and is well constructed, though the knockouts are not punched well. The switching mechanism functions fine and has good contact in both positions. This will function fine for the intended application, which is not connected to the main grid. It will not pass electrical code in my area. I felt it was a bit pricy for the quality of a switch rated at 100 amps.
