Check: 2.9% < 5%.

: Determine the total power consumption of the equipment. cable calcs

$$\Delta V = 6.71 \text Volts$$

: Cables that are too small for the load will overheat, potentially melting insulation and starting fires. Check: 2

$$\Delta V = \frac0.86 \times 120 \times 651000$$ Check: 2.9% &lt
