    Evening ladies and gents..:)


    The backbox is a 47mm deep one and total depth is what 52mm. I have to terminate 7 x 1.0 mm and 2 x 1.5mm in the box do you reckon there is enough room? The plate switch  will be a 6 ganger, and I envisage using Wago's. Cheers guys.

    I've incorporated your advice Lec into the design- 12 lights in total a switch for each bank of 6 - I was going to switch the lot on with one switch -  flipping heck.

    Is that 6 banks of 2lights JP ?  bet you get fed up operating all 6 switches when you want the lights on

    you would get all them at a squeeze into a single 35mm box

    Evening LD - no its a 6 gang switch going into the box. Two banks of 6 = 2 switches. cab lights = 1 switch, exterior lights = 1 switch, lights above breakfast bar = 1 switch and the 5 Amp SO's = 1 switch which totals up to 6 switches - its all loop in box. with 3 feeds.

    I was thinking with ref to loop in box and multiple circuits in said - you have to be careful when cabling up otherwise you could easily end up using wrong neutrals and stuff. Never had the problem but you have to concentrate. I might use markers, and I look forward to using Wago's for the first time.

    Even with all that spay foam you still want a couple of fixings from box into substrate

    As you tighten up the face plate it will be trying to pull the box forwards
