Adding ground lead to heater and band-saw.

  1. I bought a 120-volt carpenter`s band saw and a Sears
    portable heater from a friend. It works great but not
    without some minor wiring repairs. The original cords
    didn't have a ground lead, cracked left exposed and
    over used so I replace them with a new same gauge
    cord without a ground lead.

    The problems is that they both use chrome plated
    steel or aluminum chassis and don't have a ground
    plug. If it's normal to put in a ground plug to the
    heater and the saw then I will do so. What is a
    practical way to install a ground lead?

    TIA, Tibur
  2. Usual method is to use "3 core" flexible cable.

    Drill a hole in the case and on inside bolt on grounding lug (KPA) or
    crimp a ring connector onto green conductor (north america) in 3 wire
    flex cable (cord). Only newer nongrounded appliances/tools are
    double-insulated like a power drill.
  4. Good idea. The three core cord sounds like a good
    idea. I assume stringing or attaching a separate single
    ground wire along its cord is incorrect.

    If my heaters don't use a ground lead then it's actually
    safe to operate heaters with a stainless steel surface?

    How do we avoid getting shocks from touching an
    indoor 1500-watt heater?

    TIA, Tibur
