I need to replace my x3 old 'fuse holding style' consumer boards for modern trip style, but noticed a couple of things while researching them:
1. Why do they come pre loaded with various MCB's? Surely it's best to add whatever amperage you require as there will otherwise be some which are not required, and have to replace with others of different rating? Mine for example is made up of 3 boards - No 1 has 4x5a, 4x30a, 1x32a, No2 has 5x30a, No3 has 6x5a, 1x30a. I'm hoping to combine 1 & 2 into one 15 way boards as they're next to each other so would be neater, but all the 15way board I've looked at don't obviously cater for my circuits!
2. Have the ratings changed? eg. why 6a & 32a - is this what you'd use for a 5a light & 30a ring main circuit?
Thx
