10ft 14AWG 12V DC Extension Cable DC 2.1mm x 5.5mm 5521 Power Supply Adapter Flat Extender Cord,Female to Male Wire for CCTV Security Camera,IP Network Camera,DVRs and More Devices

Many DC cables sold are 16 or even 18 AWG. Which may be fine for small currents, and short distances.AMPS and cable length determine what size wire you need.The formula WATTS DIVIDED BY VOLTS = AMPS.Before selecting an extension cable, calculate your AMPS and look at a wire size chart with cable lengths to determine the minimum size wire you need. With wire size, smaller AWG is larger conductor size.Larger wire sizes, like this 14 AWG, help reduce voltage drop, esp over longer distances.I had bought a cheaper cable for another panel, and the plastic housing on the male end, did not come close to covering the outside metal of the connector. This one does. No gap between cable ends. It helps keep moisture out, and helps keep the connector from deterioration and heat build up. I’m kinda hoping that one fails, so I can get a 2nd one of these heavier gauge cables.
