Question: Q. An 240 volt electric wall oven has a KW rating of 7.2 Kw. What is the minimum branch circuit size permitted when used on a 120/240 volt system?a) 25 ampsb) 30 ampsc) 50 ampsd) 35 ampse) 40 amps
Here's how to solve this problem:1. Convert kW to Watts
7.2 kW 1000 W/kW = 7200 W2.
Calculate Amps
Amps = Watts / Volts Amps = 7200 W / 240 V = 30 amps3.
Oven Branch Circuit Rating Requirements
* The oven branch circuit rating is the branch circuit size required to supply that appliance. The oven nameplate rating (7.2KW) is used to determine the correct branch circuit.
Therefore, the answer is (b) 30 amps. Flag for review
