Hello and thanks for any and all advice. We are wanting to cover the meter, the 415 volt cutout box as well as a large amount of wiring in the entry way of our building which has a premises license. What type of material can we use in regards to fire regs? We are not covering the mains breaker or the mini breaker switches as they are all ready in neatly sealed units. Basically we are boxing in wiring and the electricity meter (which will obviously have an access door). Can we use MDF or do we need to use double thick plasterboard or something else? Thanks much!
