Ok, even after 30 years (and roughly 4000 set-ups & shows) I run into situations that leave me scratching my head. Keep in mind, in the following paragraph we are NOT talking about a disconnect or a company switch, but the distro that breaks up the circuit into smaller circuits such as 20s and 50s. Had a house electrician give me a hard time because my distro used circuit breakers! His point was that circuit breakers can jam and if that happens there is noting limiting the current going into the smaller circuits. True. But I don't think I have ever seen a fused distro in use! Once again, I am not talking about the company switch (fused) or a disconnect box (fused), but the actual breakout distro for the smaller circuits. Now, this was not a young guy, but a licensed electrician who has been in the biz since 1972. Anybody ever run into this? His attention turned onto the sound company who had no protection in their distribution, and later a different electrician came on duty who had no problems with breakers.
