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.

Wiring a Wall Light

Electrical Question: I am planning to run nm cable (or mc cable, whichever you think is more appropriate) from a light fixture in one wall to a new light fixture in the opposite wall. I am planning on running the cable above a dropped ceiling.

Install New Wiring Wall Light

Vince asks:
I am planning to run NM cable (or MC cable, whichever you think is more appropriate) from a light fixture in one wall to a new light fixture in the opposite wall.
I am planning on running the cable above a dropped ceiling.
My question is this: can the cable exit and enter each wall through the dry wall through a hole as is; or do I need junction boxes at each exit entry points?

In short, can cable exit enter a wall through a hole or do I need a junction box at each point of exit and entry?

Additional Comments: I am a retired college professor who wanted to become an apprentice electrician after retiring. I am currently taking care of my elderly mom. I love learning about electrical wiring and your website helps me accomplish that. Thank you for sharing your knowledge.

Wiring a Wall Outlet

Electrical Question: Hello

i hope you can help me. I live in south fla and we have bad storms here.

Voltage Surge Wall Outlet

Bob asks:
Hello

I hope you can help me.
I live in south fla and we have bad storms here.? I have all my major appliances plugged into surge protectors battery backups in different rooms throughout my home.

We recently had a bad storm which caused a power surge.? All the surge protectors battery backups in my master bedroom ONLY all began beeping and clicking like crazy.? I tried to reset them to no avail.? I tested the outlets with a multi meter and I have 121.5 v at each outlet.?

I replaced all the surge protectors battery backups in the master bedroom with new ones.? They stopped beeping but they are still clicking.? I reset the sensitivity on each unit to the lowest setting but I am still getting the clicking.?

I contacted the manufacture and was advised that the clicking is the AVR (Automatic Voltage Regulation) function working.
It acts as a filter that either boost or trim incoming voltage from your wall outlet.

None of the other units throughout the house has any issue.? It is just the master bedroom.? I also noticed that if the light is on in the master bedroom closet it flickers when the surge protector battery backup click and only when they click.? It appears the problem is only on the feed to the master bedroom.
Any help or suggestions would be greatly appreciated
Respectfully
Bob

Wiring a Wall Light

Electrical Question: I have replaced numerous light fixtures over the years without any issues. My current home is 17 years old.

Electrical Code for Lighting Wall Light

Kathie asks:
I have replaced numerous light fixtures over the years without any issues.
My current home is 17 years old.
I wanted to replace some old builder installed hollywood light fixtures in my guest bathroom with some new fixtures.
When I removed the old fixtures and attempted to align the mounting bracket of the new fixture to the wall, it looks like there arent any boxes to attach it to.
It appears that the previous light fixture was just screwed into the drywall without any anchors.
Is this something that is okay?

Is a box required?

If yes, how hard is it to install one at this point?

I am attaching photos of the two holes where the wires are coming out from the wall.
I am also attaching a photo of the mounting bracket for the new fixture.
(The screws show in the photo are the ones that are used to attach the fixture to the bracket.) I know I could probably install it the same way the original builder did, but using wall anchors to screw the mounting bracket to the wall and then make sure there is room for the screws that attach the fixture to the bracket have enough room to self adjust in the back (into the wall opening).
I just dont know if that is up to code.

Additional Comments: I haven’t looked through everything yet, but what I did see so far was very helpful.

I have replaced numerous light fixtures over the years without any issues. my current home is 17 years old. I wanted to replace some old builder installed hollywood light fixtures in my guest bathroom with some new fixtures. when I removed the old fixtures and attempted to align the mounting bracket of the new fixture to the wall, it looks like there arent any boxes to attach it to. it appears that the previous light fixture was just screwed into the drywall without any anchors. is this something that is okay? is a box required? if yes, how hard is it to install one at this point?

im attaching photos of the two holes where the wires are coming out from the wall. im also attaching a photo of the mounting bracket for the new fixture. (the screws show in the photo are the ones that are used to attach the fixture to the bracket.) I know I could probably install it the same way the original builder did, but using wall anchors to screw the mounting bracket to the wall and then make sure there is room for the screws that attach the fixture to the bracket have enough room to self adjust in the back (into the wall opening). I just dont know if that is up to code.

This electrical wiring question came from Kathie in Lancaster, Pennsylvania.
