FAQ:

Q: What does open hot mean on a tester?

Q: When to look for an open hot in a circuit?

A: The presence of an open hot is indicated when there are no lights on the tester. Repeat Steps 2 and 3 for all of the three-pronged outlets in the house.

Q: What does it mean when an outlet is open hot?

A: Typically this means that there is no power at the outlet. But the appliance worked. I looked at the label on the tester and it indicated โ€œopen hotโ€. Can anyone help me overcome my ignorance on this, and tell me what is going on?

Q: How many volts does a 3 hole outlet tester test?

A: The three lamps of a 3-hole outlet tester will light up for a range of voltages in the neighborhood of 120 volts, but sometimes a receptacle that is unable to run a table lamp can run this 3-hole outlet tester; that is, under a real load the voltage does not remain as high as it tests.
