CHAPTER $20$ Special$-$Purpose Outlets for Ranges, Counter$-$Mounted Cooking Unit

$5.$ The NEC permits the following wiring methods to supply household built$-$in ovens and ranges. True or false? $($Circle the correct answer.$)$

a$.$ Nonmetallic$-$sheathed cable

$($True$)$

$($False$)$

b$.$ Armored cable Type AC or Type MC

$($True$)$

$($False$)$

c$.$ Flexible metal conduit

$($True$)$

$($False$)$

$6.$ For electric ranges that have a calculated demand of $\frac{83}{4}kW$ or more, the neutral conductor can be reduced to $q,\%$ of the branch$-$circuit rating but shall not be smaller than $.q,$ tWG$.$

$(7)$ One kilowatt equal $q,-$ Btu per hour.

$8.$ Older style electric ranges had heat control knobs that had "indents" that could be felt when rotating the knob to adjust temperature to three, five, or seven different heat positions. Most new electric ranges have control knobs that do not have "indents." This type of heat control is known as a$($n$)q,$ heat control.

$9.$ When an individual branch circuit supplies a counter$-$mounted cooking unit, what Code reference tells us that it is "against Code" to apply the demand factors of Table $220\mathrm{.}55$ and requires us to calculate the load based on the appliance's actual nameplate rating?

$q,$

Wall$-$Mounted Oven Branch Circuit $\frac{?}{{?}_{\frac{?}{?}}{?}_F}$ and Free$-$Standing Range

To what branch circuit is the wall$-$mounted oven connected? $$

$(2.)$ An oven is rated at $7\mathrm{.}5$ kW $.$ This is equal to

a$.q,$ watts.

b$.q,$ amperes at $240$ volts.

$(3)$

a$.$ What section of the Code governs the grounding of a wall$-$mounted oven?

$q,$

b$.$ Dy wnat metnoas are wall$-$mounted ovens permitted to be grounded?

$q,$

What is the type and ampere rating of the overcurrent device protecting the wall$-$mounted oven in this residence? Hint: Refer to the Schedule of Special$-$Purpose Outlets in the Specifications. $q,$

$q,$

Approximately how many $ft(m)$ of cable are required to connect the oven in the residence?

$q,$

When connecting a wall$-$mounted oven and a counter$-$mounted cooking unit to one branch circuit, how long are the taps to the individual appliances permitted to be$?q,$

$q,$

The branch$-$circuit load for a single wall$-$mounted self$-$cleaning oven or countermounted cooking unit must be the of the appliance. $-$ rating
