In basic terms, you want to know which one is the live and which one is the neutral.
Bare off both ends of the run of pyro mark one single wire at one end with a red tape and short it onto the outer copper sheathing.
at the other end of the run of cable, with a meter& buzzer,test between each of the two bare wires to the outer copper sheath of the cable, whichever one sounds the buzzer, then that one is also marked red with tape, the other is the neutral and marked as such

Mineral insulated cable sounds like extremely OLD wiring.
1- If it is 2 insulated conductors and a ground wire, then you strip back the mineral insulation and should see two plastic coated conductors and a bare copper wire (ground). There should be a white wire and a black wire.
2- If the cable is round and not flat, the third wire should be red.
3- The colored wires (red and black) are the line or hot wires.
4- The white is common (neutral) and the bare is ground.
Hope this helps - Good luck and turn off the power if you are going to work on this circuit ! ! !

Do you mean a newly terminated cable?? If so you first have to test the insulation resistance, then determine the continuity of each conductor and mark each one accordingly with tape or coloured sleeving applied to the tails.

that should not at all ensue, look right here, giving blood exceptionally randomly is extremely intrusive to ones very own freedom's, it truly is why we don't see this form of issues in maximum activities. human beings act like it incredibly isn't any vast deal, specific in spite of, once you get carry of a few unusual guy displaying up at your door randomly inquiring for blood some circumstances a 300 and sixty 5 days then you definately are unlikely to be chuffed approximately that. it incredibly is an invasion of privateness project and something maximum men do purely no longer decide to do. everyone that announces in yet in any different case is stuffed with krap and that i desire them to bypass all the way down to the crimson pass the following day and supply some blood if its no vast deal. i've got given blood until eventually now and it incredibly is something i do no longer likely plan on doing lower back except I could desire to.

Your question cannot be answered as it stands, we need more information as to exactly what you think you are trying to do.
A polarity test is part of a sequence of tests on an installation, so your question is not rational.
Besides the test is the same for all types of cable.

A little more info would have been nice. You need a meter to see which wire is the hot to ground.
