Testing romex line?


My sump since I bought the house hasn't worked. The plug is dead and I couldn't trace it as the basement Is finished.

A little while back i finally labeled the line as dead and ran a new line. Just today I found a romex line with a disconnected near a junction box and I couldn't help but wonder if that's the same line that fed to that outlet.

How can I test this without Hooking it back up to the main power line?

I didn't want to just connect it to the 120 in case it led somewhere else and had another purpose.

You could use a multimeter and test it on ohms.

After you make sure it is dead on both ends, connect the white and black on one end and test the other end.

expose both wires at both ends...ohm to ground see nothing bounce on the meter the wire aren't grounded/or touching each other. disconnect one pair at one end...should get 0.00 on meter in ohms setting showing dead short ...remove connected wires from each other read again no reading those are the wires for the sump
