I wasnt entirely sure how to best word my title, but I am currently facing the challenge that while installing and wiring all my electronic components in their target location I need the cables to be significantly longer than they need to be when my installation is assembled in order to have enough room to perform all the soldering and contacts. To avoid having cables dangling around inside that box I would like to create one or two loops with those cables before the final assembly.
What will be the effects of doing this? The cables are 18 AWG with a thick silicone insulation and will have 5V DC with small currents < 500mA. The total length is roughly 50cm (1.6 feet) and when wound the length will be reduced to half of that. I am manly asking this question because in the army I was always told to completely unspool every cable that I use and was wondering if that is only applicable to those high voltage and high current cables or not.
