Wiring a Garage Workshop
Electrical Question: I am planning a workshop in my garage where I will have 220 volt equipment.

Workshop Wiring Project
I am building a home hobby workshop to run a 220volt, 2hp industrial lathe, stick welder, and 2HP sander.

Each machine will be appropriately fused at the ON/OFF machine switch, so the 30 Amp dryer breaker will not play a role (of being over rated) on a 5 Amp, or 20 Amp machine for example.

I would like to make use of a 220volt 30amp dryer circuit in my garage. Bring the 220Volt, 10/2 drier cable into an industrial electrical enclosure (6 x 8 x 5) from the laundry room into the garage (laundry room and garage are back to back), the Cable will be connected VIA  Hubbell HBL7810D Disconnect Switches, 30 Amp 600V, allowing me to switch between the dryer and garage.

My last resort is to run a short extension into the laundry room, through an access hole in the wall and use the Dryer Plug as required when working in the garage. An extension cord is classified a temporary installation, needs no inspection, although it is somewhat inconvenient.

This home electrical repairs question came from: Svata, from Brampton, Ontario, Canada.

Thanks for your home electrical question Svata

Power Design for a Garage Workshop

Application: Wiring a 30Amp Sub Panel for a Workshop.
Skill Level: Intermediate to Advanced – Best performed by a licensed electrician.
Tools Required: Electricians pouch of hand tools and the various power tools necessary for installing the garage sub panel.
Estimated Time: Depends on the type and size of the panel and available access to the project area.
Precaution: Any existing electrical wiring within the immediate area that may interfere with the installation of the sub panel should be identified and turned OFF and Tagged if necessary.
Notice: Installing additional garage electrical wiring and a sub-panel should be done according to local and national electrical codes with a permit and be inspected.

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.
