30 amp to 50 amp conversion

If the breaker that trips is the one at the pedestal, the problem is not on your rig, and the expense of converting all that stuff will be unnecessary.

If the pedestal breaker trips, it is probably because it is worn out and needs to be replaced. Every time a breaker trips, it gets a wee bit weaker. Eventually it will trip at the drop of a hat. If this is the case, besides breaker replacement, a cheap fix is a 50 amp to 30 amp pigtail that’s will enable you to plug in your existing 30 amp cord to the 50 amp circuit.

Your AC draws about 15 amps. If you run a hair drier (5 amps) and a coffee maker (5 more amps) and the microwave (another 7amps) along with every light in the house, it it true you can exceed the 30 amp capacity of your electrical system. In which case, you might find that trading up to a rig already wired for 50 amps is cheaper than rewiring your current one.

A hair drier will draw much more than 5 amps. Usually around 12 (most are 1500 watt). Anything that creates heat is a big amperage draw. Another killer is a vacuum cleaner. Power management is key in these type of situations and many people forget things like the hot water heater (another heat source, hence big power user) and the battery charger/converter are drawing amps without anyone noticing they are on.
If he is tripping the breaker on the pedestal repeatedly, using an adapter to plug into the 50 amp receptacle is likely to be a very marginal improvement, at best. He will just stop tripping the breaker at the pedestal and start tripping the main breaker in the rig instead. Both will be rated at 30 amps and the variance between the two will likely only be an amp or two.
