Tap conductors supplying electric ranges, wall-mounted electric ovens, and counter-mounted electric cooking units from a 50-ampere branch circuit shall have an ampacity of not less than 20 amperes and shall be sufficient for the load to be served. The taps shall not be longer than necessary for servicing the appliance.2. The neutral conductor of a 3-wire branch circuit supplying a household electric range, a wall-mounted oven, or a counter-mounted cooking unit shall be permitted to be smaller than the ungrounded conductors where the maximum demand of a range of 8 3/4 kW or more rating has been computed according to Column A of Table E3704.2(2), but shall have an ampacity of not less than 70 percent of the branch-circuit rating and shall not be smaller than No. 10 AWG.Fire Prevention and Building Safety Commission; 675 IAC 14-4.4-204; filed 11/26/2019, 11:43 a.m.: 20191225-IR-675190330FRA
