attic conversion too 3 small bedrooms

[i=p/u]

hi all.. have been asked to price for attic conversion and on my first look around today they say all the cables existing running around the ceiling need to be jigged around to suit new joists.

the cables run mostly on top of a piece of wood where the truss's meet at ceiling level, and they would like me to cut the the cables and bring around the edge of the attic where the storage space will be, but to me it looks like 2 junction boxes for each cable which seems way to much work. i have suggested to cut notches in new joists and sit the cables in these... and that will save a lot of junction box connections..

so if you can take my thoughts in, id be greatfull for some of your knowledge experience in finding a better solution if there is one

You can get them in various sizes, generally red for 1/1.5mm, blue for 2.5mm and yellow for 4-6mm. Over this they are usually non insulated so you will need heatshrink. Make sure you give them the 'yank' test to ensure they are tight.

for the lighting cables, i would replace the affected cables from fitting to fitting etc, with new cables, re-routed through the storage areas. then there will be no joints. for the sake of a few m of 1.0/1.5mm, far less faffing about.

Personally, I'm not a fan of crimps on solid core (yes, I know this debate has been done to death). However, if that's the way you intend to go, then blue crimps will be the size you want for 2.5mm. If you can, go for the ones with the heatshrink as part of the crimp as it makes a nice job.

Tbh, I'd be surprised if the ratchet tool was very good for £20, but I may be wrong...

I stand corrected then.

Mine is an elpress unit which was left at the factory I used to work in by a German engineer. They didn't want it back so I called dibs. Turned out to be worth about £300....

poser...you should be using gold crimps with that.

I didn't actually think anything of it at the time. Whenever we had a new machine delivered the installation and commission guys would be there for about a week and would always leave something behind....
I was actually looking for spare dies for it for different types of crimp when I came across the price. My jaw hit the ground somewhat.
That said, it is a damn fine bit of kit.
