How to Use:
- 1. Place the automatic transfer switch of the dual power supply on the debugging platform, and connect the corresponding power line according to the correct phase sequence. The phase line and the neutral line are connected in position, and the wrong connection is not allowed.
- 3. When debugging the three-pole switch, the common and spare neutral wires should be connected to the neutral terminal (NN and RN) respectively.
- 3. Set the dual power supply automatic transfer switch to work in the self-turning and self-resetting mode. If the voltage of the two power supplies is normal, the switch should be placed in the common power supply position, and the common power supply is closed.
- 4. Set the common power supply NA, NB, NC, NN for any phase loss, the dual power supply should be automatically converted to the backup power supply, if the common power supply returns to normal, it should be converted back to the common power supply

The screw shells are too small for for the amp rating. There is no way to get wire with the rated ampicity into the lugs.

Despite its small size, this is a full featured transfer switch with extra contacts for monitoring. Contact switchover is rated You can set it for manual or automatic operation, but can't switch that remotely, only monitor which power source is active. In manual operation there is a red rotary switch to select the source. It's very stiff and you will absolutely not switch it accidentally.Overall this is a good economical way to change my standby generator over without manual intervention (provided it starts successfully!). I'm not using a whole house generator, so the switch rating of 100 amps is overkill in my case, but I couldn't fit anything larger than 10 Ga. wire through the terminals, which is going to limit the amount of current I can use substantially. A 100 amp switch needs to be able to connect 0 Ga. wire.

Hello everyone. This product is of very poor quality, it has not been connected for a month and the coils have burned, I have bought from several brands and the end is the same, the contacts are burned or damaged (they move from their position because the supports are damaged) anyway. It doesn't even hold half the amps they claim to be, an average of 6 transfers have been damaged in different facilities, the auxiliary contacts often don't work, bad, very bad, the worst
