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.

    I have a Kenmore Model C970-47121-3 built in oven. The hookup cable has red, black, white, ground, and a yellow wire. Where does the yellow wire hook up to? I do not have any a manual for it. The yellow wire goes back to the oven light switch.

  2. Dave Rongey says:

    Hi Wayne,
    My search for a wiring diagram for this oven returned little that was useful. I will post this for all to see and maybe we can get more information.

    Due to the expense and differential failure rates, I am replacing my existing cabinet mounted wall-oven/microwave combo unit with two separate units (a single oven and a stand-alone microwave) in the same space. The problem I’ve discovered is that the old oven provided its own 120v power supply to the microwave using a standard 3-prong receptacle. The new oven does not and there is no 120v outlet or wiring in the cabinet space. Since the old microwave/oven combo shared the single 220v, 40amp 4-wire circuit despite electrical codes requiring a dedicated breaker for the oven, I am confused as to whether or not I can tie-in to the existing oven circuit to provide a standard 120v outlet for the microwave as a matter of code compliance. Also, I am not certain as to how I would tie-in if it did comply. Thanks, in advance, for any help you can provide.

  4. Dave Rongey says:

    Hi Chris,
    When installing separate units as you have described, the new oven and the new microwave will require separate dedicated circuits that provide their own level of circuit protection. The old oven provided internal fused circuit protection of lower amperage for the outlet specifically for the microwave component, which is a common practice that is code compliant. Unfortunately the new oven does not have that feature, or the two units are not sold as a set. Aside from installing an additional circuit for the new microwave, one option would be locate two units that are sold as a set that do have the same setup as the old oven.
    Enjoy your new ovens!

  5. chris says:

    Thank you, Dave. This is what I suspected and after looking at the old unit, I can see that the oven’s power supply for the microwave has is protected by a 20amp fuse. Unfortunately, for me, I already have purchased and have taken delivery of a new wall-oven unit and microwave so it will be cheaper and easier to find a way to tie into the common kitchen GFCI circuit… maybe pull a new line in from the breaker box. In any case, it sounds like a local electrician will be getting another small job.

    Again, thanks for your quick response, and I hope this helps some of your future visitors.
