Question 1
A 240-volt, single-phase, 30-ampere clothes dryer circuit is being installed in a
residential unit. What is the minimum demand load that must be calculated for this dryer
according to the NEC?
A) 3,000 volt-amperes
B) 4,500 volt-amperes
C) 5,000 volt-amperes
D) 7,200 volt-amperes

RATIONALE: NEC Article 220.54 states that the load for household electric
clothes dryers in a dwelling unit shall be either 5,000 volt-amperes (VA) or the
nameplate rating, whichever is greater. Since a 30A, 240V dryer calculated value
is 7,200 VA (30 x 240), but standard standard nameplates typically fall under 5,000
VA, the code sets 5,000 VA as the minimum base baseline demand load if the
nameplate is not higher.
