Question 1 of 10
What is a branch circuit, according to NEC?
NEC Article 100 defines a branch circuit as the conductors from the overcurrent protection device to the final circuit element.
Question 2 of 10
What is the typical load considered per outlet in the 'Outlets per Circuit Method' for general purpose loads?
The article states that the general-purpose load per outlet is typically 1 Amp or 120 Watts.
Question 3 of 10
How many outlets might you connect on a single 15-amp lighting branch circuit if using the 'Outlets per Circuit Method' and the anticipated load is high-wattage?
If the anticipated load is high-wattage, connect 10 outlets per circuit.
Question 4 of 10
What is the minimum load requirement per square foot according to NEC Article 220.41?
NEC Article 220.41 specifies a minimum load requirement of 3 VA per square foot.
Question 5 of 10
What is the approximate area one 15-amp circuit can cover when using the 'Per Square Foot Method'?
The article states that a 15-amp circuit can cover approximately 600 ft².
Question 6 of 10
What is the 80% rule primarily intended for?
