Convert Existing Circuit Wiring
Electrical Question: Can I convert the circuit wiring in my shop to be used for different equipment?

Jives in California asks:
Due to an abundance of ignorance of the different amperage of 220v power I purchased a table saw with a 220v 15amp motor. My shop is wired with 220v by the guy who came before me. he put in two 30 amp breakers and one 60amp for some big 3 phase woodworking machines. However, the power going to the outlets is single phase.

One of the 30amp breakers has two outlets with twist lock receptacles. is it possible to switch those outlets for two 15amp outlets or can I remove one of the 30amp breakers and put a 15amp in its place and 15amp outlets? I have worked with electricity and I am handy with tools and instructions but I have never worked in a breaker box. I am into DIY so I am game for new skills, but not so much at the cost of my life if at all possible.

Additional Comments: Great resource for DIY!

This electrical wiring project is about Circuit Wiring in a Garage Workshop of a Home.

Converting the Circuit Wiring

Jives, from the information you have provided, existing circuits may be converted as long as the wire type and size supports the amperage and voltage for the new circuit usage. If the wire size is larger that the proposed new circuit that is fine, however the wire size cannot be smaller that the new circuit power requirements. Also, the circuit breaker amperage must be the same as the outlet amperage, and all of the circuit wiring changes must have the required identifications, such as color coded electrical tape that is applied for the purpose of identifying the purpose of the each wire, at the circuit breaker panel, and at each outlet and device where any circuit changes have been made.

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.
