Question

The maximum number of lumineers that can be installed on a 20 amp 277 v branch circuit is _______. Each lumineer will draw 72.6 W at 277 V. These lumineers will not be operated continuously.

Answer 1

The maximum number of lumineers that can be installed on a 20 amp 277 v branch circuit is 76, calculated by dividing the total power capacity of the circuit (5540 watts) by the individual power draw of each lumineer (72.6 watts).

Step-by-step explanation:

The maximum number of lumineers that can be installed on a 20 amp 277 v branch circuit is determined by first calculating the total allowable power draw on the circuit.

Since the lumineers will not be operated continuously, we can use the full capacity of the circuit for our calculations.

First, we find the total power capacity of the circuit by multiplying the amperage by the voltage. So, that's 20 amps × 277 volts = 5540 watts. Each lumineer draws 72.6 watts.

Therefore, the maximum number of lumineers that can be installed is the total power capacity divided by the power draw per lumineer, which is 5540 watts / 72.6 watts per lumineer.

Now, we perform the actual division: 5540 / 72.6 ≈ 76.25. Since you cannot have a fraction of a lumineer, round down to the nearest whole number.

Therefore, the maximum number of lumineers that can be installed on a 20 amp 277 v branch circuit is 76.
