IEC connector with fuse and switch

THANK YOU

Yes, thank you willgolf! That is indeed the direction they have gone on mine, as determined by listening.

SO, on my amp(PASS Labs x250.8), the center contact is oriented to the LEFT and the fuse points in/out, NOT UP/DOWN....any thoughts?

“if the iec input is oriented so that the center contact is below the contacts on the left and right, then the hot is on the right side, and the arrow should point to the left”
@jw944ts, 

Going by the advise from TweekGeek, you would insert the QSA fuse with arrow ⬆️ pointing towards XLR/RCA inputs.

@lalitk,I appreciate you trying to help, but perhaps you didnt understnad my post....the use is oriented from the BACKSIDE of the amp toward the frontside, so neither of your suggestions are helpful
