Is It OK to Use a 20amp Tripp Lite Isobar Surge Protector Suppressor Instead of a 15amp?

Pretty sure a 15 amp breaker should “trip” before the 20amp trip lite?..

Use a 50 amp if you can find one.  It is not providing overcurrent protection.  the higher the current rating, the less likely it will negatively affect the performace of your amp.

@raysmtb1 Would that be for medical grade?  My health is pretty good.

It’s not gonna work as well unless you spend at least $2000😆

Yep, that's fine.

The Furman with SMP/LiFT are better, joul-less units, but the Tripp Lite are a close second. :)

I use Furman Elite 20PFI - a 20A conditioner/surge protector on 15A breaker.  It has 20A style socket on the back, but it came with two cables - 15A plug and 20A plug.  It suggests that company approves it on 15A mains.  I believe the only consideration is that wiring is done with sufficient gage for 15A circuit.  Anything above it is even better.

I think so. It's a surge protector, it's not waiting to see 20 amps before it trips.
