Older Home Electrical Wiring Problems
Electrical Question: I bought a 5 year old house here in Southeast MO, in a county with no building codes or inspectors.

This electrical wiring question came from: Joe, a Homeowner from Poplar Bluff, MO.

Thanks for your electrical wiring question Joe.

Working with Older Home Electrical Wiring

Application: Upgrading Older Home Electrical Wiring
Skill Level: Intermediate to Advanced. This electrical project is best performed by a Licensed Electrician.
Electrical Tools Required: Electricians Pouch of Hand Tools for Rough-In Wiring, Electric Drill and Auger Bits,  Extension Cords, and Ladders.

Estimated Time: Depends on the extent of the project, the type of wall coverings and structural construction and available access to the project area.
Precaution: Any existing wiring in the immediate area that may interfere with the installation should be identified and turned OFF and Tagged.
Notice: Installing additional electrical wiring or upgrading existing electrical circuits and wiring should always be done according to local and national electrical codes with a permit and be inspected.

  1. Cesareo Galindo, Jr. says:

    My parents have a very old house where the two wires that run to the outlets and switches are both wires. How do I wire an outlet or switch.

  2. Dave Rongey says:

    Hi Casareo,
    A non-conductive voltage tester is great for identifying the black wire of the power source in a case such as this. Another method is to use a standard voltage tester where one of the tester leads is connected to a grounded source, or an extension cord ground prong when the extension cord is plugged into a grounded outlet.
    I hope this helps,

  3. Ramiro says:

    When it rains in my area the power to an outdoor outlet goes out for a couple of days. Could the wiring be getting wet?

  4. Dave Rongey says:

    Hi Ramiro,
    If electrical wiring or electrical components get wet from rain or any moisture then the electricity can use the moisture as a path to the earth or a ground source. Electricity will travel or flow using the least path of resistance, including water. This is a dangerous condition that could be a potential shock hazard that should be corrected. The solution would be to inspect the wiring and devices in the affected area and correct any sub-standard wiring that is not compliant to current electrical codes, and make sure that moisture proof circuit components are used. Above all, proper GFCI protection should be installed.
    Be Careful and Be Safe!
