When the switch is on grid power, the grid feeds to the two bars. When the switch is to generator power, the generator power feeds onto the two bars.
If you wanted to send power to another panel, you would attach the cables to the center bars as well.
You also need to know if you have 3 wire input or 4 wire. If 4 wire, then you have to know where the neutral is bonded to the ground. Hopefully, someone will come along here and explain bonding for you better than I can.
the bond should be in the breaker enclosure at the meter, so he should have four wires in the conduit he wants to intercept.
also you can not mount that switch like you have it in the pictures, the conduit has to be below any live parts in the switch, unless you use myers hubs into and out of each side.
have you got another quote yet?
