[QUOTE="wildej, post: 530958, member: 35240"] Couldn't seem to find anything that would cover off a situation where I want access to switches on the front of the panel, but also have enough depth between the front of the enclosure and the rail to allow front entry cables that obviously don't come out of the front of the enclosure or require the cables to bent aggressively. I was instead thinking of doing the attached. This puts the RCBO and two transfer switches in a generic circa 12 module CU enclosure (good quality of course) and uses two Techna DB35 DIN rail mounted distribution blocks (which are top/bottom entry like an normal MCB/RCD etc) for splitting the LINE connections. It then uses the two NEUTRAL screw terminal blocks that are generally in a CU anyway for splitting the neutrals (but keeping them separate as is necessary for the separate DP isolation). Obviously need to earth the metal enclosure as well. What do you think of the attached? This seems to me to work in practice. It provides a single 'distribution panel' for all of the isolators associated with the battery storage in one place, that can be easily labelled and understood. It removes a whole load of single tails that would need double isolation, clipped to the wall linking separately enclosed devices and switches. However, does it fall foul of some regulation that I'm not aware of (quite probable giving my lack of knowledge)? I'm aware that it is good practice to generally only use compatible devices (MCB, RCDs etc) in a CU, whereas this mixes different devices. However, this seems to be done commonly anyway and this isn't actually a consumer unit installation in the conventional sense, just a enclosure for distribution switches. Thanks again! [/QUOTE]
