Pull the sheathing off with your fingers, and inspect the wire beneath to make sure no damage has been done. There's no NEC requirement that the end of an abandoned cable, energized or not, be inside a junction box. However, you can combine methods to strip wires fast. Tape each wire nut onto its respective wire with electrical tape. Some of the methods are fast, whereas some are considerably slower. Readers should refer to the Standard. Cap the wire ends with wire connectors or wire nuts. But if you don't want to discontinue the circuit entirely, or it is problematic to remove the cable, you can safely cap the wires and terminate the cable inside a junction box. You can easily make this yourself at the garage using the items listed above. "paymentAccepted": "Cash, Credit Card", Shut off the power to the electrical circuit by switching off the appropriate breaker in your home's service panel (breaker box). The applicable Australian Standard for connectors used with copper cables of cross-section area greater than 10mm2 and aluminium cables of cross-section area greater than 16mm2, is AS/NZS 4325.1:1995, Compression and mechanical connectors for power cables with copper or aluminium conductors, Part 1: Test methods and requirements. Note: Another option is moving this to right above cabinet height to allow for the ability to plug in lighting with a basic receptacle - if you don't want to remove the wire. When you remove or open an interior wallor a ceiling, you may encounter stray electrical wires. The tester should indicate no voltage.

Disconnect the switch or outlet you are removing. If you are still going to do the job yourself beware (apart from the obvious Electricity can kill) new plaster attacks copper cables after a while so make sure you full wrap the cables up and ideally cover them with a small metal plate before the wall is plastered so in the future you cant drill in the cables accidentally and get a shock! Once the end sheathing has been separated, go ahead and pull it off. The electric wire strippers are a little more costly than the manual wire strippers are. }, Australian General Engineering There is a socket behind a radiator in my house can't use it but it remains one to show there are cables and two so if radiator replaced with Myson type there is power for it. Following the requirements will ensure performance, safety and long service life. However, if the ends of the wires are mangled, snip them back until you reach a smooth section. An example of a mechanical wire could be a Guy-wire, but this guide will focus on electrical wiring. The DC voltage drop is also measured along a second separate but known length of test conductor (known as the reference conductor). These are the items you will need for this method. It is quite slow. For example a clock output or even just a socket blanking plate.
