Is Your 240 Volt Outlet Safe
|
Examining a 240 Volt Circuit and the Electrical Wiring Components for Safety – The wire gauge of the circuit should be verified. If it is found that the circuit wire AWG gauge is #12 then the circuit breaker amperage size could be increased to be a 20 amp 2 pole circuit breaker. |
Examining 240 Volt Circuit Components
[ad#block]Electrical Question: I have a dual 15 amp 2 pole circuit breaker that outputs 240V to a single 240V 20 amp outlet.
- Is this acceptable?
- It was installed when the house was built 20 years ago.
- I’m concerned about the safety of the electrical wiring.

Thanks for your electrical wiring question Jeff.
Examining 240 Volt Circuit Components and Electrical Wiring for Safety
- Because the 240 volt receptacle outlet is rated at for 20 amps then the circuit wiring should be 20 amps.
- The wire gauge of the circuit should be verified. If it is found that the circuit wire AWG gauge is #12 then the circuit breaker amperage size could be increased to be a 20 amp 2 pole circuit breaker.
- If the AWG wire gauge is found to be #14 then the 20 amp 240 volt receptacle outlet should be replaced by a 15 amp 240 volt receptacle outlet and the appropriate cover.
- You may see that there are a few different types of 240 volt receptacle outlets available, such as straight blade and twist lock, 3-wire and 4-wire configurations.
- The correct receptacle outlet should be selected to be compatible with the 240 volt circuit and the application or 240 volt equipment that will the receptacle outlet will be used for.

The Safest Way to Test Electrical Devices and Identify Electric Wires!The Non-Contact Electrical TesterThis 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 TesterThis 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 CutterMy 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. |
