How do I calculate my AC voltage drop over a specific wire awg?
How do I calculate my AC voltage drop over a specific Distance?
Pelco Cameras, Pelco Transmission & Power
- Cameras (analog)
- Power Supply
- Wire Awg type
Camera is not powering up over a given power wire awg and a given distance.
View the following chart for wire awg distances.

Example if you have a Spectra camera that uses 73VA from a power supply, the wire is 80 feet from camera to power supply. You would have to use a minimum 16 Gauge wire for power.
Same Example as above but distance changes from 80 feet to 150 feet from the camera. You would have to use a minimum 14 Gauge wire.
NOTE: MAX SIZE IS 14 GAUGE WIRE THAT WILL FIT IN TERMINAL BLOCK FOR POWER.
