Hi all
I need to run some FP200 to an automist fire dampening system. I have already cut holes in the hallway walls and cut notches in the studs. Where the cable enters the walk-in in cupboard where the boiler and and consumer unit are (which will be the location of the pump unit), I plan to to use p clamps and surface mount the FP200. The people fitting the system say that a non switched FCU must be installed. In their pre-install literature they show a picture of a plastic flush mount FCU. Given that I am going to be using surface mount cable, shouldn't I use a surface mount metal clad box (with appropriate compression glands)?
The FCU needs to have its own C class MCB. I have told the customer that as it will be a new circuit, I am not allowed to do that part. However, I want to ensure that the electrician has everything to hand when he turns up.
I plan to use these glands for the metal clad surface mount FSU
Will the above suffice for FP200 entry in to the the new metal Hager CU?
Another concern that I have is that, from what I have read on the manufacturer's installation guide, the plasterboard must be no thicker than 14mm. The wall that will have the spray plate is 18mm ply with plastered plasterboard (about 30mm). I have already cut the opening for the box, do I need to enlarge it so that I can cut away some of the plywood? I guess that the limitation is a result of the entry of the "hose" pipe into the back box.
Thanks in advance.
