I Would like to suggest a new upgrade option..
FUSES!!!!!
it would have some cost but be available say 1 lapis 2 HV cables and 6 glass
= glass
= HV cables
= Lapis
The item will short out/break if you ever overcurrent or do anything that would cause the machine to break from a electrical option.
As long as the burnt out one is in.. it wont pull power and wont destroy the machine..
