Default Do mains RCD's reduce dynamics?

Hello,

I'm wondering how much a simple and unavoidable mains circuit RCD reduces amplification dynamics?

I ask as I've recently had my house consumer unit replaced with a regulation dual RCD type which isn't a problem as it's unavoidable, but my system is in an outbuilding which has it's own RCD/MCB's running from the house consumer RCD/MCB's, so now my systems AC has to pass through 2 sets of RCD/MCB's.

Bit of a mouthfull I know, should I bypass the 'outbuilding' RCD?

Any opinions on RCD's??





Thanks

For those of us who are in N.A. what are RCD and MCB?
My thought would be that RCD's are Ground Fault Current Interrupters.
That MCB's are circuit breakers?
But what is the real meaning?

They don't affect dynamics and safety is important, so you may as well leave them in. Think about it, if you can run a 3kW electric kettle through an RCD without it dropping excess volts why would it have any trouble with the hundred or so watts of an amp?

It's audio mythology spread by the technically illiterate, forget about it.

Now that I know what RCD's and MCB's are. Nether will affect the quality of your AC power. The RCD sensing circuit has no effect on more and the failure mode contacts have less effect than a wall plug. The MCB small resistance and contact have no effect also.
