Overcurrent protection for residential cooking equipment. NEC, 422.11(B), 210.19(A)(3) & 220.55.

I know how to calculate the branch circuit to cooking equipment, I know how to calculate the load for a service for these items but I get a little confused as to how to properly calculate the overcurrent protection for residential cooking equipment, especially when I have a separately fed oven and cooktop.
Would taking the nameplate at 100% (adjusting up to the next standard cb) be correct or would you adjust per 220.55 to size protection, or would you do something else. I never gave it much thought until a student of mine asked exactly were the code addressed this...

Overcurrent protection of the appliance branch-circuit per 210.20 in conjunction with overcurrent protection of the appliance itself per 422.11(E).

When in doubt, follow the manufacturer's installation instructions in compliance with 110.3(B).

As an inspector be aware that a sharp electrician may use Table 220.55 Note 4 to use a single 40 amp br. ckt. and tap connections to the cooktop and wall oven per 210.19(A). Tap rules have been around for a long time. I have inspected several industrial sites with taps and high-bay overhead drops. Please review 240.21(A) and look over part (B) and (C) for future reference.

I thought that tap rule only applied to 50 amp Range/cooktop/oven circuits. I do not think a 40 amp circuit may be tapped for this application. Am I wrong?

(3) Household Ranges and Cooking Appliances. Branchcircuit
conductors supplying household ranges, wallmounted
ovens, counter-mounted cooking units, and other
household cooking appliances shall have an ampacity not
less than the rating of the branch circuit and not less than
ti]83&#826he maximum load to be served. For ranges of [color:#3366FF][0;4[/i[/color]] kW or
more rating, the minimum branch-circuit rating shall be
40 amperes.
Exception No. 1: Conductors tapped from a 50-ampere
branch circuit supplying electric ranges, wall-mounted
electric ovens, and counter-mounted electric cooking units
shall have an ampacity of not less than 20 amperes and
shall be [i]suff&#305[/i];cient for the load to be served. These tap conductors
include any conductors that are a part of the leads
supplied with the appliance that are smaller than the
branch-circuit conductors. The taps shall not be longer
than necessary for servicing the appliance.

What the heck happened to my reference? The forum server scrambled part of it.

What part got scrambled?

I think what we tend to forget is 220 is load calculations not actual installation.

I high lighted in blue the part that was scrambled. It is a minor detail.

I am listening, explain please. My reference is Article 210.19(A)(3).

I think Ruben was just making a generalized statement that Article 220 is used to calculate loads for branch-circuits, feeders, & services & that Articles 110, 215, 230, & Chapter 4 are used to determine required conductor & overcurrent protection sizing; as applicable.

Yes sir, my question is: can we do that tap thing for cook tops off a 40 amp circuit as was stated earlier by another member?
