Connection armoured calbe to twin and earth cable
I understand how to terminate armoured cable in a metal box using a
gland kit, but what should one use to connect the tails to the twin and earth cable in the metal box? -- Posted via Mailgate.ORG Server - http://www.Mailgate.ORG |

Choc block of the appropriate size is fine, or you could crimp the joints. Are you using one of the SWA cable's conductors as an earth, or using just the armour for this? Either way, the armour needs to be connected to the T&E's earth wire. the simplest way to achieve this is to use a piranha nut on the gland, and attach a short fly-lead to it. -- Cheers, Roger ______ Email address maintained for newsgroup use only, and not regularly monitored..

You should run an extra earth wire outside the cable and connect that to the
box also. "Roger Mills" wrote in message ...

mused: You should run an extra earth wire outside the cable and connect that to the box also. No you shouldn't. If the cable were below ground then you'd have to run the earth in something to mechanically protect it, which negates the need for the SWA as you may as well run it all in that then. If you want to run a seperate earth the preferred method is to use a 3 core armoured for single phase supplies. -- Regards, Stuart. |

The armour of SWA cable is perfectly adequate as a protective conductor, if terminated properly and then looked after. The energised conductors are connected via a terminal strip as is the protective conductor. The metal box should also be properly connected to the protective conductor. Should one wish to run the protective conductor inside the armour and some more insulation this can be done using a three core cable. However, the armour and box must be connected to the protective conductor too. -- David Hansen, Edinburgh I will *always* explain revoked encryption keys, unless RIP prevents me http://www.opsi.gov.uk/acts/acts2000/00023--e.htm#54 |
