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 Main Panel

Electrical Question: I bought a tiny one bedroom adorable house built in 1897, half the house is still knob and tube wiring. Someone apparently made an effort to update it with romex, but didnt get very far, the wiring up in the attic is knob & tube, but the wiring coming into the breaker box is new, which seems strange.

Install New Wiring Main Panel

Brett asks:
I bought a tiny one bedroom adorable house built in 1897, half the house is still knob and tube wiring.
Someone apparently made an effort to update it with romex, but didnt get very far, the wiring up in the Attic is knob & tube, but the wiring coming into the breaker box is new, which seems strange.
So.
one fine day a storm came and power went out, when it came back on, it hicupped and stuttered a bit, but came on.
It was about 10 minutes later that I went to the bathroom, and discovered that a breaker had obviously tripped, and wont turn back on, so I am working through that to find what got fried, and well I am at it I figured I would add a breaker for the furnace.
It just seems to me that a furnace deserves its own circuit.
: ) Anyway, digging around through the old school insulation and spider webs is kind of annoying so I figured why try to find and fix whatever happened to the knob and tube, Ill just replace it all.
So that is what I am doing and of course theres a few issues .
when they updated what little they did , I dont see any ground wires coming in to the box, and for that matter the box doesnt seem to have a ground bar.
I have to say I am not sure how to recognize one, lol, theres a neutral bar on the left side , and on the right is in unused bar but I dont see a green screw so that is why I am not sure.
I find it strange that all four breakers, (small house : ) , are on the right side with a wire connected to the pigtails going up and around to the left side neutral bar.
Why not just put the breakers on that side, and connect the pigtails right there?

Anyhoo, all pigtails are covering this unused bar, would that be the ground Bar?

Theres no ground wires except for the one on the 220 line coming in for the dryer, and strangely, the ground wire is bent straight down after having just come in up from the bottom and doesnt connect anything.
I have been using the dryer for 4 years now and every time I use it I think about that stupid unconnected ground wire, as well as the lack of any other ground wires.
I cant dont see any metal conduit anywhere.
So.
my question is are,.
1, why no ground wires?

2, is the bar on the right side the ground bar with no green screw?

3, why not put the breakers on the left side for easily connecting the pigtails directly to the neutral bar?

4, what do I do with my ground wire for the furnace, and the future lines that replace these, connect them to the neutral bar?

.
or to the unused bar on the right side, which btw, is bonded(?

) across to the neutral.

Additional Comments: What’s the catch?
