Did electrician set up my dedicated subpanel correctly?

OK I got it, nice clean set up. It is dedicated and to a room not just a single or double run. Same way I did it. I use wall mount 220/40 AC units in the listening room. The AC is not in the same box I ran all 4 AC units in a separate 100 amp sub too. I like sub panels. I have one for every addition in my home. The new main is going in with the solar plug and sub panel.

I'm going with a trailer vs roof mount. The maintenance, batteries everything is easier.. Just plug and play. I don't have to worry about solar thieves either at a few of the place I go . On guy his whole cabin was moved solar in all 4 miles away.

Like I told him when I tracked it. I don't have to find every track just the next one.. YUP stole his whole cabin. How much time do you get for stealing a whole house? LOL

Enjoy.. 

The EP-2050ee is a parallel whole house surge protector, waveform corrector and power conditioner. Because it's parallel, it won't limit current. The EP-2750 ground  filter provides additional filtration of the safety ground for the dedicated audio circuits. I've done the same in my homes.

The four 20A branch circuit breakers are installed on both Lines, legs. Two on L1 and two on L2.

What is the main 2 pole breaker ampere rating? I can’t read the number on the breaker handle.

Any idea the size of the feeder wires feeding the main 2 pole breaker? My guess is #6awg copper. If #4awg or larger the electrician would have installed a plastic bushing on the feeder box connector.

As for the installation and workmanship it looks good. I would have probably installed the EP-2050EE SPD straight across from the 2 pole breaker it connects to. The shorter the leads the better.

@jea48 Thanks for mentioning keeping the two black wires from the EP as short as possible. Recommended by the manufacturer for best results.
