    I don’t have a green ground wire or a bridge ground for my three prong dryer cord. Is it safe to hook it up without grounding the dryer?

    • Dave Rongey says:

      Hi Jose,
      It would not be safe to hook up a dryer without the protection that an approved bond to the ground system will provide. The dryer must be properly grounded to an approved ground source using approved wiring methods. A dedicated circuit for a 240 volt electric dryer should be installed as required.
      Be Safe!

  2. Pam McMurray says:

    Bought a new whirlpool Cabrio dryer. It has 3 prong plug connection so I used plug from old dryer (also 3 prong). The instructions that came with the dryer say that the ground wire on the dryer should be disconnected and added to the center ground wire of the three plug connector. Then it says to connect the dryer ground using a separate copper wire “to an adequate ground”. What would that be?

    • Dave Rongey says:

      Hi Pam,
      The source for an adequate ground for a dryer plug or receptacle would be the ground wire of the dryer circuit. This ground wire is typically the bare copper wire or a green insulated wire which is part of the dryer circuit cable. A ground wire is required for all 120/240volt home electrical circuits. The only exception would be where the circuit wiring is inside a continuous electrical metallic conduit which has been installed with methods which are compliant with all applicable electrical codes.
      I hope this helps,
