Keep in mind that any given piece of equipment will only draw as much 'power' as it needs. If you 'upgrade' to 4 gauge wire for your projector and plug it in to your 14/2 outlet,your not likely to notice ANYTHING except a very unruly wire that is hard to configure into an attractive 'loop' to your projector! It will still only draw 4 amps! It doesn't matter if you use djy's 'super conductor' or the supplied cord.
Every day is a good day.......some are just better than others!
