Shock or tingle, or doubts about a ground.

A licensed electrician should do the live readings, ground path tests and any bonding corrections.

Customers put it like this

  • I felt a shock from the outlet
  • the washer gives me a tingle
  • my old house has three-prong outlets
  • I am not sure these outlets are grounded

Stop first if

  • Someone is still in contact, or a person is in water.Do not touch them. Call emergency services and shut off power only if it can be done without risk.
  • A metal case or grounded part gives a shock or tingle.Take it out of use, keep people away and call a licensed electrician now.
  • Lights also shift bright and dim, or several metal parts feel live.Keep everyone clear, then call the utility and a licensed electrician.

Ask on the call

Homeowner? These are the questions a good technician will ask you. Having the answers ready makes the first visit count.

  1. Is anyone hurt?
  2. What were you touching, and where were you standing?
  3. Is it still happening, and can people stay away from it?
  4. Does it happen with one appliance or in several places?
  5. Are these three-prong outlets in an older house with two-wire cable?
  6. Has there been generator, EV charger or subpanel work lately?

  1. Take any case or part with voltage out of use first.
  2. Treat a correct plug-in tester result as a screen only. A false ground jumper can read correct.
  3. On three-prong outlets over two-wire cable, press TEST on the upstream GFCI. If the outlet stays live, treat it as ungrounded and unprotected, and refer it.
  4. A qualified person compares hot-to-ground against hot-to-neutral, then reads from the metal case to a known ground.
  5. With the switch off, a qualified person reads from the lamp shell to ground. Reversed polarity puts the shell live.
  6. On a dead circuit, a licensed electrician tests continuity from box to panel ground, and looks for extra neutral-ground bonds.
