Thanks for your electrical question Robert.

Electrical Panels and Electric Dryer Circuits

  1. Robert, all of the electrical wiring connections should be checked at the electrical panel, especially the lighting circuit.
  2. This may be an indication of a loose electrical connection or a deteriorating connection with one of the main incoming lines at the panel as well.
  3. This should be checked by an experienced electrical contractor.

  1. David says:

    I replaced a dryer line and plug. When the dryer was turned on the lights on first floor dimmed down to 20 percent.

    • Dave Rongey says:

      Hi David,
      From what you have described it would be best to turn off the dryer circuit. The circuit wiring methods and the connections to all of the components should be carefully examined to determine any possible fault.
      Please note that electrical wiring should be installed with a permit and then inspected by authorities representing the local jurisdiction.
      I hope this helps,
