Fuse or braker for dedicated lines?

Still puzzling over this breaker vs. fuse issue & I'm just wondering...
Both devices have a buss input contact point & a load output contact point. However the breaker has an extra set of contacts internally (the switch part) that the fuse does not. Could it be the additional micro-arcing that occurs across the breakers's internal switch contact that makes them noisier?

Regarding line conditioning: I use Chang Lightspeeds which were in-circuit during the aforementioned "experiment". Whatever upline power changes occurred was not masked by these filters.

One other thing about breakers: the very worst kind to have for sourcing an audio rig is a ground fault type breaker - they're extremely noisy.

Just want to add that in talking to people in Nth America, Europe , UK, Aust and here in NZ, it is marked that independent experimentation has revealed a preference for ceramic fuses. And this has been my experience too.

Hi Bob. Thanks for your email.

Hoping to move right along to further insights (as opposed to bickering over old ones) - one of the most useful things in my experience, is to regularly call up the local electricity supplier and complain of noise on the line and ask if they could come out and clean and tighten the connections (again). And they send a man-in-van out to clean and tighten the connections feeding my house. It is very noticeable the morning after it has been done - and I am not at all confused about which night they do it.

redkiwi: where i live, all our lines (electrical, telephone and cable) are underground. the main electrical connection to the breaker box is via conduit. hence, i'm not sure whether our gas and electric supplier COULD clean and tighten connections. moreover, i'd fear having someone just look at our electrical box would result in a $200 charge on our next utility bill! guess you have much to be thankful for in NZ. -kelly

I am indeed thankful to live in NZ Kelly - just a shame that our incomes here mean your US gear is very difficult to afford. My financial state could use some US-style income right now. Albert Porter's experience with getting a dedicated feed from his local utility (large transformer feeding just his house) suggests there are some local wrinkles you might look into.
