Warehouse Job

[Dave 85]

Hi lads
Just looked at wiring a warehouse about 20m by 20m and thought I'd get some opinions on a few things.
I've done a bit of industrial but am 95% domestic. (Not domesticated though)

Its an empty industrial unit at the mo with just a new 3phase board and nothing else. Its gonna be used as a workshop for building luxury log cabins.
So heres what im thinking:
PVC conduit run horizontaly a meter off the ground to feed all the sockets. Is this adequate you reckon? I don't do steel so its that or SWA
6 Metal Halide 250w lights, wired in SWA-Are these the best type of light? is 6 enough?
RCBO's on the sockets-Im tempted not to bother, what do u guys think?

Any thoughts would be much appreciated

Thanks for the help lads, from the sounds of it theres only gonna be one bit of hard wired 3 phase machinery but not had a proper discusion really. The prob with metal truning is that the vertical steels protude from the walls about a foot right up to the ceiling, every 6 metres all the way round. So getting past them would be a nightmare. Think this ones gonna have a tight budget so I'm not too concerned about future proofing.

a job doesnt stop because of an obstruction,you work round it,either by buying preformed bends or making your own,no matter what you use your going to have to bend round it.

lol, once did a wharehouse about 150mtrs x 100mtrs pillars about every 5mtrs had to set round every single one with 2x2 galv trunking! nightmare but looked the dogs when we'd finished!

I did one just about the same size, Used 2x2 Galv trunking, once you do a couple of bends your like a pro, You will fly through it. I simply used a jigsaw with a HSS blade on for cutting the lengths into desired sizes, and another tip drill out your mounting holes in the full lengths equally spaced so you can screw them down to a work surface whilst you cut and work on them. And besides the customer will be paying for the material don`t worry about the number of bends you need to use (2 internal & 2 external for each pillar/steel support), at least when its finished you will be very proud and pleased with yourself.

SECONDLY!!! If it`s the landlord who is getting you to do the work don`t worry about the tenants consumption or requirements, As I understand the Landlords just needs to provide A sufficient sized D/B and lighting, there on its the tenant who needs to order the remainder work to be done according to the spec`s on his machines etc... so you have two lots of jobs and customers.:devilish:

Hope this helps.

The other option is to angle bracket off the wall for a straight run of trunking, conduit out of the back and 90 degree down to positions.

decent idea,but will take longer and cost more making and fixing uni strut brackets than a few bends.

Done it loads of times, contact in an engineering works very handy. Inch angle iron, welder and red lead or spray paint. Fix a few brackets between pairs of pillars and place the system on top, drill and fix as you go along. I agree about unistrut but, if you can get brackets made up, no probs.

Im working for the tenant, that's the issue. Landlord supplied 3ph DB and nothing else. I could potentially get a lot of work outta this guy wiring cabins so I can't risk losing this job by overdoing the price. Still waiting for spec but ultimately I'll give him the choice of how it's done
