I have a ST270BH. I was also wondering about the 50 amp upgrade. I do not believe I have the wiring set up so I probably don't have this upgrade.
In looking at the converter it is a wf-8955PEC says 55 amps does this mean that it is usable for the upgrade? Would additional circuit breaker(s) upgrade and new cord be all that is necessary?
Tried searching but have not really found any info and would like to know what is needed before I asked around for prices.
