"This consumer unit is a 8 module not 4 module with 6 usable ways for mcb's. If fitting rcbo's you will find it a bit tight at the top. This board doesn't come with any labels ie main switch/rcd or a neutral link or buzz bar. However It does have a neutral and earth terminal bar. Be careful taking of the protector film from the door as you have to remove the door to remove the protector and it is very easy to snap the plastic lug which hinges the door. Does look nice once installed."
