CAn I use a 20amp fuse in a fuse box that says 30amp?
i was planning on changing all 4 fuses in this box . there not broken but i figured with age they would blow.
this one fuse i wanted to change from a 30amp to replace with a 20amp. reason being the wiring in the room that is connected to that fuse is old so if something were to ever happen, i didnt want the wiring to get to hot. so i assume i could use a lower fuse so that if something were to short or whatever, the use would blow before a fire.
would that be acceptable thing to do? (asside from rewiring the whole room)
