Hello all, I want this to be a electrical FAQ thread. I am a small personal grower looking to expand my experiences to a larger more productive grow. When I started to research what exactly I needed to do, to upgrade my power. I came up pretty much empty handed. I am assuming installing a 100 amp sub panel into a house isn't normal. I couldnt find any information that was simple enough for me to understand. So this is for all of us that are not licensed electricians, as harm reduction. I DO NOT suggest attempting this unless you hire a electrician or are in company with someone with a strong background in HVAC and electrical experience.

Ok to start off golden rule water below waist and electrical above waist. With that being said I will start with my purchases.

A titan controls co2 regulator. 3-8" inline fans and four 6" inlines. And tons of other random equipment that i have accumulated over the years

Im worried that the wire was not thick enough but my brother (who has more experience then me) said this was the right size. Its a 4 strand copper wire thats all i know.CAM01176.jpg

The wire looks really thin compared to your typical extension cord wire. But my brother explained that 220 runs off of 2 hots and 1 ground. So to the room there will be two of the wires running to the sub panel. I think the wire is too thin. He looked it up on the national electrical code website or what ever and it said 4 gauge he said 4 gauge and 4 strained is the same. Im not sure if it is, and doesnt sound right to me.

Assuming a 90c THHN your good to 90a on the sub panel feed.

Your load feeds are all nm-b jammed through the SE knockout in the top of the box. This indicates too much fill for that conduit size or no conduit and improper fittings / no fittings used to secure those feeds at the panel knockouts.

You don't use a main breaker on a subpanel since it's overcurrent protection is installed at the service point.

Green bonding screw only used at service entry, never sub panels.

Whoever did the electrician job has the same level of aptitude for this endeavour. I can't dumb it down much more. Grab a copy of the NEC and see how complicated it really is.

Ive done some electrical work myself. But i am limited at this point and I am hoping to learn and share what I learn, hopefully without burning the house down. I know snaps if you need it to be dumbed down you probably shouldnt mess with it in the first place. But thats not me Im the stoned DIY guy. My only choice is to learn
