Fuse
Hi
It seems like something is wrong with my printer. As soon as i try to heat up the bed or hotend the fuse breaks. I don’t know why because it used to run just fine.
thanks for any help

Which fuse are we talking about?

the fuse that is on the plug that goes into the wall
What size fuse and what is the bed wattage and voltage?

it’s a 5a 250v fuse and a 120v 1500w bed
but it was working before
1500 watts / 120 v = 12.5 a. Your bed pulls much more current than your fuse can handle
Precisely what Vitamin G said, You have exactly what I have and I run 2 separate circuits, one for the 1500 bed with a 15 amp fuse and the other for electronics with a 5 amp fuse.
I'd also like to mention that you should not just arbitrarily increase the size of your fuse on your socket. You need suitable wiring to match the current you will be pulling. For example, extended exposure to currents of 15 amps on 18 AWG copper wiring is a fire hazard. If you plan on a set up like Cgrr mentioned the 15 amp circuit should have no less than 14 AWG wiring to handle that much current for extended periods of time. I mean no disrespect if you do not have good knowledge of electricity I highly suggest having a licensed electrician handle the mains wiring.
I'm lucky where I have my VC500. I was able to easily run a real 20A wall socket and 12awg wires to a 20A breaker in my garage breaker box to power my printer.
I have a push button style small 15A circuit breaker on the printer just for the bed, and a separate 5A breaker for the rest of the system.
power cord from wall to printer is 14ga
