Agreed as well. What can happen is that if someone mistakenly believes that
by viewing a 30A breaker that one may also draw 30A from an existing 20A
plug/outlet combination without first looking closely at the rating of the
plug/outlet. The nomenclature can be difficult to read and/or understand
for non-electricians.
Last month, I took the costly plunge of upgrading my twist-locks from 20A to
30A for system congruency: I had an existing 30A breaker, #10 AWG wiring,
but upgraded to a 4-pole 30A twist-lock plug/outlet combination.
The Alpha amp electrical cabling was also upgraded to #10 to better match
the current rating of the 77Dx amplifier. The only drawback is that
stranded #10 is pretty darn hard to flex and needs a rather large bend
radius! Thankfully, Dick Ehrhorn had the foresight to use high-current
Cinch-Jones electrical connectors on his early amps which made the upgrade
much easier than if the #10 cabling had to be pulled into the amp chassis
via a strain relief.
