Did electrician set up my dedicated subpanel correctly?


I’m green when it comes to all this stuff. I had my electrician set up 4x dedicated lines in a separate subpanel for my listening room. I also gave him 1x EP-2050EE to install and 4x EP-2750 ground filters for each dedicated line. From this subpanel I’m running 4x 10-2 w/g CRYO Romex to 4x Furutech GTX-D NCF(R) receptacles.

Does everything look okay to the experts here or does anything stand out? One Q I had was if each of the dedicated lines needs to be on the same side of the panel?

Thanks

Good question.  People always say "call a licensed electrician" like they never make mistakes.  I always double check their work and often end up changing it.  I grew up in the construction industry and knew a lot of people I wouldn't let change a lightbulb in my house.

Picture looks professionally done.  10 gauge is correct.  

I don't know about the filters you used. (that is not a figure of speech, I literally don't know.) 

But generally I would not put something like that on a high power circuit, i.e., my amp. 

Are all 4 circuits on the same leg?  (red or black, usually).  that is a recommendation but not always important.

The ground filters are coils with heavy gauge copper.  They are fine, but excess.

I'd suggest a surge protector in this panel and your main as well if you are at all concerned about surges.  In 2020 the NEC began to require them for life safety issues. 

When you say dedicated what do you mean?

It looks like a dual 15 (220/240) and an extra 20 in in the same box. It also looks like the 15s are 2 x # 14 and the 20s are on # 12. The Green looks like # 10. 

I'm missing something here? The orange cable coming in the top is the cryo?

It this one room or something with an AC wall mount or something in it too?

It's dedicated to a room maybe, but not to sound. The panel is set up clean no doubt. But dedicated NO. Will it work, yes, perfect.. 

please add some cob webs. :-)

Yea, the 2x 15 amp is to power the EP-2050ee (SPD+Noise filter). The extra 20 amp is an unused spare. The orange cable is the cryo.

Confused what you mean it’s not dedicated, oldhvymec?

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.
