This is second post, this time regarding CU. The unit I have inherited after buying house is a Wylex 10 way High integrity board. it has a 100A isolator and two 80A 30mA Rcd's. However while it is a flexible board with the neutral busbar split in to three, it has been altered by linking the neutrals to a be a 100A main switch incomer consumer unit. I would like to change this situation to take full advantage of the Unit and use it as a high intergrity unit splitting the circuits across the two Rcd's and use RCBO's off the main switch for alarm and for fridge freezer.
However i would like to check the final circuits prior to changing everything over and then discovering a problem or problems. i was advised to get a Megger MIT220 tester to do this but is it the right one to go for?
Many thanks in advance. i have done 2330 pt2 and 3 a yr ago but not done anything with it yet but hope to with this house and moving forward
