Just because a pedestal receptacle reads 256 volts doesn’t indicate how many amp can be drawn.
If the EMS or breaker is tripping it could be overheating from not enough amp bring able to be drawn through that breaker or loose connections causing amp drop. Undersize wiring can do the same.
You can run 250 volts across a small 18 gauge wire but it can’t flow but a couple of amps without melting, shorting or device kicking off.
I’d say low amperage is the problem.
