Since this is a purely resistive load 5500 watts at 240 volts is 23 amps, breaker is sized at 30 amps and 10 awg wiring is used. In your case if the elements are strapped for 4500 watts draw is 18.75 amps, permanent draw loads should be sized at 80% of breaker capacity so a 20 amp breaker is limited to 16 amps.
In this manner, how many amps is equal to 1 watt?
For example 12 watts/12 volts = 1 amp.
Converting Amps to Watts.
The conversion of Amps to Watts at fixed voltage is governed by the equation Watts = Amps x Volts.
For example 1 amp * 110 volts = 110 watts.
How much is 1200 watts in amps?
That's because watts = volts x amps So if you look on the back of an electrical device (or on a lightbulb) and it says 1200 watts, and you live in the U.S. or Canada where your house has 120 volts, then: 1200 watts = 120 volts x 10 amps Houses in other parts of the world have electricity that is 240 volts.
