Hi, I'm making some modifications to my central heating and hot water system in a cupboard. The old 'wiring centre' was a single gang plastic pattress box, which was pretty scary and literally crammed full with wires. Conventional wiring centres don't have enough space, so I've put in two 100x100 adaptable boxes next to eachother which gives plenty of knockouts and wiring room to accept flexes from valves, pumps e.t.c. at the bottom, with the T&E from thermostats, programmers boiler e.t.c. coming in the back. I'm trying to do it as neatly as possible, I'd have rather used one large box but there simply isn't enough length on the existing cables, so I opted for smaller boxes with shorter terminations.
I still have 8 flexes I need to terminate: two motorised valves, 2 circulator pumps, a flow switch and 3 thermostats. At the moment, I've connected all the neutrals and earths using large 30a choc blocks, but I'm going to have an extra 5 or so more wires to connect together and I also need to bond the boxes. Is there is a better solution to connecting multiple earths/neutrals in junction boxes? I've considered the 5-way lever wago connector, but I'd need about 3 of these, so maybe one in each box. Any thoughts? Also, do you think another 100x100 adaptable box might be needed for the last few accessories?
