    Hi Chris,
    The Ceiling Fan Blue Wire
    These typical the light fixture wires found on most ceiling fans:
    The blue wire is the power, and the white wire is the neutral.
    I hope this helps,

    I would like to add a lamp to a ceiling fan. After removing the cap covering the wiring I see a white wire (common?) and a blue wire which I think might be the hot wire. Please advise,
    Chris Payne

    Hi David,
    Yes, a GFCI outlet may be wired to knob and tube wiring as described in the instructions found in the article: Knob and Tub Wiring and GFCI.
    To help verify the polarity of the knob and tube wires a non-contact voltage tracer may be used.
    The label which comes with the GFCI outlet must be applied to the face of the outlet which states that the outlet is not grounded, however the GFCI circuitry will still provide ground fault protection.

    Be Careful.

  4. David Yurick says:

    I have a question regarding knob and tube wiring. Is there a safe way to wire a 15 amp GFCI outlet to knob wiring?

    Thank you.
