Having just had a partial damp course installed, I am taking advantage of the pause before the plasterers arrive to replace the rather old and dubious radial circuit that provides power to downstairs in our house with ring cicuit. Although I am happy with the details of the wiring itself, I am looking for advice on the type of pattress box to use. The choice seems to be plastic boxes that only have punch-outs for the cables at the rear or metal boxes with punch outs at the rear, sides, bottom and top. The plastic ones seem preferable as they do not have to be lined up exactly with the level of the (future) plaster but they are awkward to install because the cable has to enter from the back. Is there a reason why plastic boxes with cable entry at the bottom are not available? Could I just drill holes in the bottom of the boxes?
Thanks for any help
