Electrical Wiring for a New Garage
Home Electrical Question: I have a new post garage. It’s of pole construction, sided and roofed with metal panels. I plan on insulating and sheet rocking it.

I need a plan to wire it. I have some experienced wiring helpers to deal with the digging and actual wiring. I know how to run wire through walls and underground. I have 200 amp service. I have 4 “bays” for breakers under my meter. I have 2 phase service. I think I want to install a sub panel (this would be sub panel No. 1). Connected to this sub panel is the hot tub (it is wired through sub panel No. 2 further down the line) with 2 circuits (20 amps each), 1 is an out door outlet used on the BBQ.

The other powers a lighting circuit in a shed. The shed and outlet were wired by a full time electrician. The shed and hot tub sub panel would be serviced though the aforementioned sub panel (No. 1) through a 50 amp breaker. The garage will have 1 220 VAC outlet (30 amp 220 VAC Small dryer style plug outlet)to service a compressor and a 220 VAC welder. Each of these do not draw more than 30 amps each. I plan on installing only 1 220 VAC outlet to service this equipment, so that both cannot be operated at the same time. I will have 9 110 VAC outlets around the perimeter of the garage with the possibility of adding 4 more in a possible expansion at some date in the future.

I will have Florentine lighting overhead, 3 or 4 rows of 5 each 4′ 2 tube fixtures. There will be a garage door opener, hard wired or plugged to an outlet in the stringers (this is included in the outlet count above. there will be a 110 VAC LED light by the man door and an 110 VAC LED area light above the roll up door. I Think I can do this with 100 amp breaker in the No. 1 sub panel to the garage (wire run underground through 1.25″ conduit) w/ copper wire to a breaker box rated at 100 amps with a main (100 amp)breaker.

I have a fused disconnect for the welder and compressor that would be hooked up to a 50 amp breaker in this Main (sub panel No. 3?) panel. The wall outlets would be GFI protected from the first outlet down stream to the end, I think this should be divided into 2 separate circuits. The overhead lighting should be 2 desperate circuits too. The local inspector told me I need 2 grounding rods hooked up to the box and 4 wire service from the No. 1 sub panel to the garage. The pic is my MAIN under the meter I get 220 VAC with a tandem breaker in the middle; leaving 1 single space on each side.

Electrical Tips to Help You Wire it Right

The Safest Way to Test Electrical Devices and Identify Electric Wires!

The Non-Contact Electrical Tester
This is a testing tool that I have had in my personal electrical tool pouch for years, and is the first test tool I grab to help identify electrical wiring. It is a Non-contact tester that I use to easily Detect Voltage in Cables, Cords, Circuit Breakers, Lighting Fixtures, Switches, Outlets and Wires. Simply insert the end of the tester into an outlet, lamp socket, or hold the end of the tester against the wire you wish to test. Very handy and easy to use.

The Quickest Way to Check for Faulty Electrical Wiring!

The Plug-In Outlet Tester
This is the first tool I grab to troubleshoot a problem with outlet circuit wiring. This popular tester is also used by most inspectors to test for power and check the polarity of circuit wiring.
It detects probable improper wiring conditions in standard 110-125 VAC outlets Provides 6 probable wiring conditions that are quick and easy to read for ultimate efficiency Lights indicate if wiring is correct and indicator light chart is included Tests standard 3-wire outlets UL Listed Light indicates if wiring is incorrect Very handy and easy to use.

Strip Off Wire Insulation without Nicking and Damaging the Electric Wire!

The Wire Stripper and Wire Cutter
My absolute favorite wire stripping tool that I have had in my personal electrical tool pouch for years, and this is the tool I use to safely strip electrical wires.
This handy tool has multiple uses:
The wire gauges are shown on the side of the tool so you know which slot to use for stripping insulation.
The end of the tool can be used to grip and bend wire which is handy for attaching wire onto the screw terminals of switches and outlets..

The wire stripper will work on both solid and stranded wire. This tool is Very Handy and Easy to Use.
