In Reply to: RE: Audiophile-Grade Circuit Breakers Demand? posted by dcuhl on July 15, 2014 at 08:48:32
Why not purchase the Square D type NF panel
You will get bolt on connections, larger frame size and internal components
Higher frame bracing
This is the best one could ask for in a home

I think you may be missing the point. I am suggesting audiophile quality breakers in 15, 20 and 30 amp sizes, to populate the box. Not the box itself.

dcuhl,
I believe you missed deafbykhorns point. The panelboard he suggests is a commercial/industrial grade panel. And it is listed for use in the USA.I notice you keep posting the use of a 30 amp breaker for use to protect the branch circuit. If the receptacle/s that will be connected to the branch circuit are 15 amp and or 20 amp rated receptacles then that would be a code violation to connect them to a 30 amp breaker. The largest breaker handle size for 2 or more 15 amp rated receptacles and or a 20 amp rated receptacle/s is 20 amps.
Just using Square D QO or QOB (bolt on) breakers for an example the size of the current carrying delivery metals from the panel bus connection, the breaking contacts, and load connection terminals are exactly the same for a 15 amp, 20 amp, 30 amp, 40 amp, and I believe 50 amp breaker. The only difference in the breakers is the magnetic trip and thermal overload trip settings.
A 30 amp breaker should never be used when 15 or 20 amp rated receptacles are used. There is absolutely no need.

Understood. I thought 30 amp was a bit excessive, but I was trying to be inclusive to others current demands. Still 15 and 20 amp audiophile grade breakers is my desire and the potentially huge difference that they could make. I'm quite curious as to the specifics of the Isoclean/Siemens breakers. What's plated, what's different and how their construction is different, etc.?
