Camera Install

[scottpitts]

I need to calculate cable size for the following camera install. I'll have 220v source and the runs will be 5600' over that run will be 5 camera locations each with a 5amp max load for equipment. What size cable should I run? The cable will be in PVC conduit attached to an exiting chain link fence.

Camera nameplate seems huge. I doubt you can run these from a single 25A circuit (NEC 422 violation), so you may need two. And what is the true voltage -- 220 isn't a system voltage. It would be 208 or 240. What does the camera draw at that voltage? Pan/til/zoom could be part of the load which helps as that isn't constant, but even then 5A seems too large.

That current is large unless there are also things like an enclosure heater, radio transmitter for the comms, light source, etc. That said, it would be better to know both the actual wattage needed and the utilization voltage(s) of the equipment.

You might want to price out running 480v and putting a small fused transformer at each location; that would let you do a single 20amp circuit and cut the wire size. Also think about running two circuits so that one fault doesn't take out all the cameras.
