    Your description is a bit confusing to me. But I can say this... I have never seen a residential fuse that would break the circuit, then come back on. When a fuse blows, it's done and needs to be replaced. I'm thinking you have another problem that should be examined immediately.

    If you have a meter, you can check both ends of the fuse for 120 volts to ground. You can also check the leads coming off the fuse holders. Since you are dealing with heavy conductors, it calls for steady hands. It may be safer to do your probing with the disconnect open and using the ohm scale. All the connections should have a very low reading.

    Without a meter, all you can do is replace the fuse and see if it fixes the problem. That may also fix a fuse that was making poor contact.

    Thank you for the help all of you,but we figured it out and it wasn't a fuse after all,the huge plug that goes to the out side box(on the pole) was spliced last year for my pool filter and 2 of the wires were barley touching,which explain the on and off,so went to Lowe's and all better thank god

    To Cobraguy:

    I've seen 2 intermittant 3AG fuses in my life so far. The first time drove me nuts. Ohms test OK. Put in circuit it opens. Go figure.

    That would drive me nuts too. I've never seen it. But I'll remember it! Thanks for the information.
