Hi,

I have run two armoured cables between a new detached garage and the house.
I would like to know the correct terminal boxes/glands to use to route the cable through the house wall. Do you use water proof boxes on the outside and then strip away the armour and only route the cable through the wall to the terminal box?
I have an electrician coming to connect up both ends garage and house but I wanted to route the cables through the wall and drill any holes etc so I can tile around the drilled holes and tidy up ready for the fuse box to be fitted.
 
Take the cables through the wall intact. Do not terminate them.
 
I'd leave the hole to the spark as well, unless you're in a trade yourself, chances are he'll have a more powerfull faster drill and the right sds bit for it too, I certainally wouldn't knock anything off a price for the sake of having to drill a couple of straighforward holes in brick!
 
Leave it all to the electrician - depending on the quality of your consumer unit he may wish to terminate the SWA in a box mounted alongside your CU. Many modern plastic CU housings wont take much strain with an armoured gland especially if a side entry - top and bottom not usually a problem.
 
The issue with SWA is it isnt very bendy. Most SWA is underground, comes vertically up a wall and needs to turn 90° to go through the wall.
If you try and do it as a single run you'll always have a big loop sticking out from the wall.

Unfortunately, this situation makes an unbroken run a bit of an issue.
Here's the way I've done the throught the wall trick, but it often needs a junction - inside is best.

But, really, as above.
Leave it all to the electrician
