Sounds like you have a TN-C-S arrangement.

If you have a balanced mains supply (presumably by using a 1:1 transformer with a centre tapped secondary), you have two 'live' or phase lines feeding your gear. Therefore the balanced secondary need to protected by two fuses, or a ganged RCB.
Therefore the minimum cost of entry is £100. And unless the fuses are marked and conform to BS1362, and a fault occurs which damages your gear, your household contents insurance will be invalid.

My BMU has dual pole RCBO's fitted on Primary and secondaries, so safety and regs wise, all good.
I wouldn't recommend anything else with a balanced setup, especially not "normal" fuses.
Not sure it works that way anyway.
But for a normal 13A mains fuse, on a distribution block for example,
You'd only need 1 fuse.

Fair enough, but my comments concerning possible household contents insurance still apply. Insurance companies will do anything to limit any claim, and if a fire was caused and any fuse in your system did not conform to BS1362, I wouldn't be surprised if they rejected the claim.

Oh, that old chestnut.
I think my system is pretty "transparent", but I don't feel the need to try a directional fuse in an AC mains supply.
The blurb says it is directional, so it is only better 50% of the time?
(The real reason is I can't use mains plugs fuses, as they don't fit).
As for equipment fuses, I am not sure, I am still undecided if I spend the money on fuses, or a Benchmark preamp to drive my Mod 686.
