Acceptable Methods of House Rewiring and Remodeling Considerations
Background: Dan, a Homeowner from Honolulu
Question: I had my house rewired recently. I went to look at the wires and was surprised. For example, a wire would come from the box and go to an area of the house then into a junction box. Then several wires are spliced together and leave the box to outlets. One wire per outlet and end. Is this ok? I thought the outlets would be in a series.
Thanks for your electrical question Dan.
Dan, installing new circuits to a central junction box location is an acceptable practice for house rewiring and no, outlets are not wired in series, in fact parallel wiring is best for home electrical branch circuits. When a house is being rewired, access to the outlets and switches will be a key factor, especially to the total cost of the whole project. The easier it is to access the work, the less time it will take. The best time to rewire a home or install new wiring is when an area of the home is being remodeled and the wall coverings will be removed, such as removing the sheetrock. Installing new sheet rock is far less expensive that the labor rates for electrical contractors and plumbers.

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
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.
