Fusebox problem

kathos

A fuse went out in my out, so I replaced it. I was looking at the different ones (all my fuses were "Type P" from what the box said) and there was a chart of what the fuses were for beside the fuse box and some of them had "D" and "P" under them, I was guessing they were for the types of fuses.

Now the one I had to replace had "D" under it, but I didn't have any and at the danger of having my freezer melt down on me I just put in the "P" fuse. Should I be worried? Will my condo still be standing when I get back from work? I was planning on looking for these... "D" fuses when I head out anyway.

Or is it another case of the "P" looking mighty like a "D"?

As long as they fit into the socket it's generally not a problem. I can't find anything specific on any P or D type fuses, but as long as the voltage is right you should be fine.

Do they have any voltages or anything else written on them?

I think the P type versus D type is that one of the fuses is designed to blow at it's rated Amperage, while the other is designed to blow after the fuse exceeds its rated amperage for a short time.

I think the D is for Delay.

If the letter does in fact indicate whether there is a time delay, then I'd be careful putting a time delay fuse in lieu of a non-time-delay fuse.

Possibility of damage depends upon the device the fuse is protecting. A time-delay means the device is exposed to overload situation for however long the time-delay is rated before the fuse blows.

I have some amps that have fuses in the chassis. A blown non-delayed fuse just needs to be replaced. A blown time-delayed fuse means burning smell plus $$$ in repairs to said amp.

Putting a non-delayed fuse where a delayed fuse is expected probably won't hurt, but the fuse is more likely to blow cause it will not tolerate any time in overload. Will all your shit thaw if the fuse blows? If so you might want to invest in some ice til you can replace with an identical fuse.
