New 3 phase supply, does it have to be on a 3 phase MCB or can it go on 3 individual BS88 fuses?

[MerlinGremlin]

Just been asked the question can a new 3 phase supply be installed into an existing DB that has BS88 fuses in and all current 3 phase supplies are fed from individual fuses or does it need the DB taking out and replacing with a modern 3 phase DB with MCB'S? Just want to get what other people think and why? Thanks

Both are fine, so long as circuits meet all normal installation criteria.

I would say the BS88 fuses are better.

BS88 fuses will do the job, check the are three phases and are in sequence, Brown Black Grey / Red Yellow Blue.
