class 2 overcurrent (fuse) question-primary and secondary
class 2 overcurrent (fuse) question-primary and secondary
(OP)
I haven't had to do this in a while and found reference docs online with the info but wanted to ask if I am doing this right.
I have a class 2 control transformer 40VA (120VAC>24VAC)
and am getting different results than posted online.
To determine the fuse size I am doing this:
primary> 40/120*125%=.75A
secondary> 40/24*125%=3.75A
Is this not correct?
Thanks in advance emsguy

RE: class 2 overcurrent (fuse) question-primary and secondary
0.333..... x 125% = 0.41666...
Am I missing something?
40 / 120 x 250% = 0.75
