if you are blowing fuses, see this topic:

ignore the stuff about circuit breaker reaction time and whether amperage needs adjusting to allow for it ... an EM machine is not that sensitive. If you just had 5A and 10A breakers, you'd be ok.

if you want to use spade connectors to attach wires/a fuse to the breaker, the size is usually 6.3mm.

if you can wait a long time for delivery ... stuff like these:

or search for "thermal circuit breaker" wherever you like. e.g.:

to add to what 4max said, the gator clips are also a bit easier since the fuses can be a hassle to solder wire to. The caps like to fall off the end of the tube since the heat softens whatever seals the cap on the end ... tho it does seem to set up again when it cools.

I've never seen a game converted to ATC/ATM/ATX blade style fuses, but I think some recent games use them (jersey jack games?).

the breakers are just for diagnosis ... until you forget to replace one with a fuse when done and then it's there until you find it - after you gave up looking and made another one
