Okay so hear goes.... I want too install another 5-8 plugs for my pc repair work shop onto the existing ring (I’ve basically divided my bedroom) how would I go about doing it? do I just add a fcu and run it from that or is there something different like a 20 amp fcu I can use because it’s going too be more that 5 pc running at at lease 800w that’s not included the TVs and other hard ware for it?
