An EV supply equipment nameplate input is 40 amperes and no permitted load-management reduction applies. What branch-circuit ampacity is required?

Texas Journeyman exam practice question · Special Occupancies, Equipment & Conditions

An EV supply equipment nameplate input is 40 amperes and no permitted load-management reduction applies. What branch-circuit ampacity is required?

A80 amperes
B32 amperes
50 amperes
D40 amperes

Why C is correct

EV charging is treated as continuous in this case. Multiplying the 40-ampere maximum load by 125 percent gives a required branch-circuit ampacity of 50 amperes.

A listed welder calculation permits a supplied 70-percent demand factor on 50 amperes of rated primary current. What calculated current is carried?
Two loads are verified as noncoincident: a 72-ampere heating load and a 54-ampere cooling load. If the applicable calculation permits using only the larger, what load is carried?
A 60-ampere branch circuit is available exclusively for EV charging. With no load-management reduction, what maximum continuous EV input can it serve?
A marina load-calculation step contains 160 amperes subject to a supplied 75-percent demand factor. What load is carried for that step?
A welder calculation carries 42 amperes after applying a supplied 60-percent factor. What rated primary current was used?
