How to test outlet for power?
I have a cheap ohm meter or whatever it's called. Haven't used it in a long time. I have an outlet that does not work. I want to test the power supply to see if I have power. Do I just hold one piece of the tester to the hot and neutral wire? does it matter which one I hold where?
no..the outlet does not work. I want to test the power supply to the outlet to determine whether there is power there or not. If there is, I'll know it's just the outlet and it needs replaced.
Working with live electrical current can be hazardous. Do not attempt this measurement without the proper tools and safeguards. Always test your test equipment for proper operation before use.
Turn on any wall switches that may control an outlet. It is surprising the number of times an electrician will be called out for a non-functioning outlet only to solve it by flipping a switch. Another thing to check is that the circuit breaker or fuse is intact and that no GFCI outlet controlling the branch has tripped.
Testing an outlet can be as simple as plugging in a light to see if it goes on. Of course, always test your test equipment first. If that light doesn't work and you test an outlet and assume there is no current because the light doesn't go on, you may be in for a shock.
A more thorough way to test electrical outlets involves the use of an outlet tester. This device will not only indicate if the outlet has power, it will also indicate if the outlet is grounded and whether the hot and common wires are reversed.
The device could not be easier to use and costs only a few dollars. Generally, you plug the device in and note the pattern of the lights. The legend printed on the device describes what the lights indicate. Follow all of the instructions provided by the manufacturer.
If a outlet is identified as being miswired or does not have proper ground, you should not use the outlet until the problem is resolved. In the case of a miswired outlet or absent ground, the problem may occur at the problem outlet or somewhere else in the branch circuit. Do some detective work to determine the extent of the problem before attempting any repairs.
