You do realize that 10kilowatts of heat dissipation in any home is very dangerous right? Your only option with a 10kilowatt heat profile is to have dedicated monitoring and a server grade rack.
So a 5kilowatt home clothes dryer is half 'very dangerous'?
A 10kw residential load is very unusual, but so long as it is a modern house with 200A service and the heat is vented outside though the practical limit for a load is more like 5000W due to plug/breaker/wire pricing issues.
A 6-30R plug would be the way to go. It can do 6600W peak, taken to 80% it is 5200W.
