3 Phase Armoured Cable - need to extend cables in the middle

[airevalley]

Hi, we are installing a roller shutter door, and need to move 6 armoured cables up about 3 ft, so they will need chopping, a junction installing each side and some fresh cable in the middle.

Two questions.

1. Is there any kind of junction box that can cope with this or will I need 6 individual armoured junction boxes each side

2. Anyone reccomend an electrician in the Bradford area to do this work

Thanks

You might be able to put one of these 225mm x 150mm x 50mm Galvanised Adaptable Box with Knockouts | CEF - http://www.cef.co.uk/catalogue/products/338027-225mm-x-150mm-x-50mm-adaptable-box-with-knockouts-galvanised each side but all depends on the size of the cable and the rating but no matter what you do unfortunately it wont be cheap or look pretty.

What you are asking needs a site visit and quotes from decent sparks ..

Resin joints for each or Large adaptable box for the whole lot. Sparks job.... testing required after jointing.

Maybe extending in armoured may not be the ideal modification

Perhaps a box either side with metal trunking and bridged with singles could be considered

What size are these cables.

Hi, they look like they are 25mm thick each

Any chance of some pics of the existing installation.

unless there is an issue with vibration you would probably be better off with conduit but thats entirely up to you.
but this is a situation where you would have to replace conductors and test them thoroughly (adding extensions onto existing conductors adds more splices and more places the connections can fail)
enlisting the aid of a licensed spark in your area is the best recommendation.
