Hi all. Please pardon the amateurish question! My hobby is constructing camera traps which I use to photograph wildlife, using small "point-and-shoot" compact cameras. Currently I am working on a project that involves removing the flash unit from the camera proper and installing it approximately two or three feet from the camera (via wires run in waterproof conduit). I'm looking for some advice on sizing wires running from the camera to the flash (I desoldered the flash unit, and connected the flash unit by soldering wires from the pins on the flash unit to the corresponding solder pads on the board. I know how to look up guides to sizing wire, but they rely on knowing the current, which is what stumps me. The flash is powered by a capacitor that charges to about 300V. The capacitor is 180 uF. There is a separate trigger circuit that produces very high voltage, but I believe this is integral to the flash unit. The trigger devices sends a jolt of high voltage through the xenon in the flash, causing it to ionize and short the capacitor. I already have a prototype unit built. I used some 16 gauge stranded wire I had laying around, (I decided overkill wouldn't hurt), and my prototype works. But 16 gauge wire isn't ideal; connections with camera components, and running wires out of the camera body are problematic. And what's the down side to undersized wires? Overheating? Damage to camera components? Merry Christmas to all, and thanks for reading! Brian.
