Amps = Watts/Volts = 4.16. The smallest breaker in a house panel is 15 amps. You will need a 2 pole 15 amp breaker. On a # 14 wire you can load that circuit up to 12 amps.ou need a 50 amp breaker for 120 volt operation, though 120 volt operation is not advised. You need a 30 amp breaker for 240 volt operation.      As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.
1 The process involves the ice melting to water, the water heating from 0 Â°C to 100 Â°C, then the water boiling to steam.  The energy absorbed will be the heat of fusion + the change in temperature of the liquid + the heat of vaporization, qfusion + qheating + qvaporization.
heat = 7.2J The heat that melted the 0.9g ice = 16,974.4 - 7.2 = 16,967.2J Heat required to melt 1mol ice = 18.0g ice : Heat = 16,967.2*18/0.9 = 339,344.9J = 339kJ/mol The published value is: heat of fusion of ice is 6.03 kJ/mol There is a serious problem with these figures. I have serious doubts about the mass of ice used. It does not seem possible to me that 0.9g of ice is going to cool 97.5g of water from 43.2Â°C to 1.6Â°C I suggest that you review your figures. Particularly the amount of ice used.
