Electrical Question: What Wire Size should I use for a Workshop Circuit?
I'm installing a #4 wire for the circuit to my workshop.
The workshop is about 100 feet away from the house.
I'm planning on using #8 solid copper for my ground wire.
Does that sound correct for the ground wire size?
Thanks-
Dexter W.
Copper Ground Wire for a Workshop Circuit
Electrical Question Answer: Hi Dexter - Great Electrical Repair Question!
Workshop Sub-Panel
NOTE: This workshop will have a sub-panel installed as described below:
The #8 Copper ground wire for your workshop circuit should be fine.
I would suggest that you bring your #4 wires into a small sub-panel, preferably through a main breaker disconnect.
Make certain that you are bonding your grounds separately from the neutral because this will be a panel being served from away from your main service.
I suggest installing GFCI protection for your receptacle circuits in the workshop environment.

Thanks Dave!
I actually got with a local Electrician to do the workshop.
I'm into Electronics Engineering but Electrical is a little different and I couldn't remember the rule of thumb for ground wires.
Thanks again, you offer a great service.

How to Convert the Electrical Circuit Voltage for a Motor: There are multiple problems here. You and the electrician did not discuss exactly what the 240 volt outlet would be used for. This is a big mistake, and I'm amazed that the electrician did not ask you what the circuit would be used for.

Skill Level:
Intermediate to Advanced - Electrical Repairs and Circuit Wiring is Best Performed by a Licensed Electrical Contractor.
Tools Required:
Basic Electricians Pouch of Hand Tools, a Voltage Tester and a Multi Meter.
Estimated Time:
Depends on personal level experience, ability to work with tools, work with electrical wiring, and the available access to the project area. Precaution:
Identify the project circuit, turn it OFF and Tag it with a Note before working with the wiring.
Important:
Modifying existing electrical circuits or installing additional electrical wiring should be done according to local and national electrical codes with a permit and be inspected.
This is a testing tool that 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.
This is great to troubleshoot a problem with outlet circuit wiring, 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.
A wire stripping tool used 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.
I think your site offers the the clearest and best electrical information for homeowners I have ever seen on the net.You have given me confidence to do my own projects which I never had before. THANK YOU! Paul, from Foxboro, Massachusetts
I wish I found this site earlier, it is by far the best electrical related resource I have found on the web. George, from Scranton, Pennsylvania
