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.
Is It OK to Use a 20amp Tripp Lite Isobar Surge Protector Suppressor Instead of a 15amp?
I have my audio gear and TV plugged into a Tripp Lite 20amp surge protector. The powered speakers are plugged in separately to wall outlets. The circuit and wall outlets are 15amp. I’m sure I have less than 100watts plus the TV into the Tripp Lite. I bought a 20amp by mistake. Is this OK? If there ever was an overload the 15amp breaker at the box would trip first. I assume the 20amp would have heavier wiring than a 15 amp. I think the joule rating is the same for 15 or 20amp.
