Not yet, just being proactive instead of reactive Im not sure on what the typical draw is with 2 machines, but I just know that using extension reels, you need to be careful.
Yeah, this is why i was tippy-toe on (3). Unsure about rules/laws and if any official inspection/costs will be needed.
Switch per item is good practice and suggested anyway. Not sure what the official say is on this. If my memory serves me correctly (and what i based my original post on), school shops have a cut out per item and a teacher button for the whole room (key lock, although we shouldn't need a lockable one?)
Either way, anything is better than the current set up right?
