This is actually a good discussion. Something that many folks don't consider is having the power required to run the various machines in their shop(s). Often times I see individuals trying to run an entire "knife shop" in a garage, that has one 20 amp circuit, and they can't figure out why that breaker keeps tripping.
I've also seen instances where individuals have lost their entire shop and house because of overloading. Yes, it might cost some $$$ to get the proper upgrades for powering your shop, but it sure beats hearing the insurance company refusing to pay up when they investigate the fire in which you lost everything, and find that a circuit was overloaded and caused the fire. I can see folks rolling their eyes right now..... but it happens far more often then you'd think.
I myself had to curtail the equipment in my shops when I built my new Hot Shop a while back..... because I'd have to run a brand new service to that building..... and it just wasn't in the budget. I wanted to buy a 250lb power hammer I'd been eyeing for some time, but had to settle for the 110lb Say-Mak because of power requirements. (I know...you're saying "poor Ed")
Later on, when I purchased Orange Crush (my 80 tone press), from a close friend in Canada, the only reason I could, was because it runs off a 4 cyl kabota diesel setup to run the hydraulics. I didn't have enough electric power in my entire Hot Shop to run the electric motor necessary to run it.
So no matter what level you're at in Bladesmithing/Knifemaking, it's always in your best interests to examine how much power your shop/machines pull, and ensure that you service can/does handle it PROPERLY.
