Electric
When planning for the electric, I wanted to make sure that I had room to grow, without looking cobbled together. So I elected to used conduit for the install.
In the main shop, I have one circuit for each wall, with an additional circuit for the high outlets. The radiant heat has it's own 120 circuit.
In the machine cave, I have two 120 circuits, alternating each box. Additionally, I will feed a 50 amp subpanel there for future 220 machines.
Similar setup for the dirty work room, except that it will have a dedicated 50 amp 220 run for a welder and an additional 50 amp 220 run for a vehicle charger or RV hookup behind the barn where I park the trailers.
The office is fed by a single 120 circuit.
The lighting in each shop is on its own circuit. I elected to use can puck lights from Halo for the primary light source. I like very hot light in work areas, and more amber for the office. Farm lights from Steel Lighting Co supplement the cans. Main shop is 34 cans, machine cave and low clearance dirty room each have 12. The lights were installed inside of plywood boxes in the ceiling. This lets me reach through from below to service them and prevents insulation getting all over. Furthermore, it should help limit mice intrusion. Each box in the ceiling has conduit running between them.
Heating and Cooling
Primary heat will be by a radiant system from Menards. I bought the panel pre plumbed and a 199k NG unit for the heat source. Hoping to have that hooked up before the weather gets really nasty this winter. I have 7 loops through the floor.
Currently, the main shop is heated with a 36k mini split from Mr. Cool, 12k ton unit for the office.
I thought that my first oil change in the heat would be great...first oil change in the AC was even better!
Plumbing
Fairly standard for the bath. I adding two drop for a hot and cold hose faucet in the shower, set 16 inches off the ground because a 5 gallons bucket is 15 inches tall.
Small kitchenette for late snacks with a larger sink for cleanup.
Added one hose bib outside, with a shutoff valve to go to a future hose reel in the dirty shop.
Finally, I hooked up an old washer and dryer so I don't get the stink eye for washing my shop clothes in the house anymore.
