Welcome to the forum! I concur that a 20amp breaker needs the larger 12AWG wire then the 14AWG of the 15 amp. Simply switching out the breakers is not enough. The wire has to carry the load.

I've been an electrician for over 20 years. Don't replace a 15 amp with a 20 amp. As others have said, the wire (14 gauge) isn't rated to 20 amp. It can melt the insulation and wire before a 20 amp breaker can trip and start a fire. I've seen the aftermath of someone doing this and it's not pretty. DON'T DO IT!!

Remember the fuse is to protect the wiring not the device. So, if you pull 30amps through a circuit designed for max 20amps, you'll cause excessive heat build up in the wiring until it cooks off the insulation and starts a fire. It can and will glow red hot.

X2 on JAGIVEN comment... I do this all the time when camping. All of my outside power requirements is from an extension cord plugged into the site PEDESTAL 20AMP source. We run all of our outside lights, the greeting pole lamp, maybe a 20-inch box fan for sitting around the camp fire to keep mosquitoes off of us, momabears pot roast in an electric skillet, etc. This has its own circuit breaker and will not draw any power from your 30AMP PEDESTAL connection. I will run my Oil-filled radaitor looking electric heaters from this pedestal as well when it gets cool outside. Better to use the camp site electric instead of your propane hehe...

This is also what we use for some high power items like electric heaters, wife's hair dryer, vacuum. etc... I cary several HD extension cords with us just for this situation.

When the A/C is running 24/7 during these HOT TEMP times you are running the risk big time of tripping a breaker somewhere...

This comes under my PLAN-B planning...
