Thread: 4-way old wiring question

  1. #1

    Default 4-way old wiring question

    Hi-

    I've been doing some remodeling work in my house, and I've run across a wiring situation that is unusual to me. I was having a problem which I believe I have solved with a new switch. My question is how safe is the original wiring.

    Lights--[2 wire cable]--Box 1(3way)--[2 wire cable]--Box 2(4way)--[2 wire cable]--Box 3(3way)--[2 wire cable]--Hot

    I am familiar with the correct way to wire a 3-way and 4-way switch (using a 3 lead cable), but this wiring is from the 60s and I just wanted to be sure that it wasn't a major problem.

    Thanks,
    Chris

    If you are asking about the condition of the wiring then no one could answer the question without seeing it in person.

    If you need help with how to wire then we can help.

    Did they use BX or old Romex in the original house wiring?

    My answers are based mostly on the ICC codes. Advice given is my personal opinion and every person performing work should acquire a permit from his/her jurisdiction and get the work inspected. My opinions are not directions to follow for DIYs or professionals

    I see a problem with the diagram because of how they got a grounded conductor to the fixture.

    Basically there is safety from electrocution for adults, safety from electrocution for kids (small children like to stick objects in things), and safety from fire.

    In general the newer the wiring/devices and the newer the codes the wiring/devices was installed to, the more safe it will be.

    Can you post pictures?

    Also electrical inspectors are experts on this stuff. Might want to go ask your local electrical inspector if he or someone he might recommend could visit your house and take a look at the wiring.

    Or you could get an electrical permit to do some electrical work, then while the inspector is there, ask if he could give your other wiring a look. In my area the electrical inspectors are not very busy now due to the economy and reduced construction activity, so maybe you might find a bored inspector who would welcome something to do!
