This is a common thing to see in power amplifiers, as many have such large capacitor banks (often exceeding 30,000uF per rail for the top-end PA amps). Lots of receivers from the likes of Marantz and Pioneer had big enough cap banks to destroy the power transformer on startup without a soft-start circuit, and an MC^2 MC1250 would instantly trip a 30 amp breaker.

It would fix what shouldn't be there in the first place. Placing switch on the mains side is easier and cheaper solution. And the most important of all, it actually switches all of the thing off.

For some reason I was under the impression that it was already on the mains side, but I'm not very familiar with the device in question. That would certainly be the way to do it.
