Correct Fuse?

I use a MDL-10 for each motor, or a MDL-20 if one fuse for both. They are slow-blow fuses, so they won't pop under the start-up load
The Doyle vacs had ABC-20 ceramic fuses on each motor, and within three months every one had blown for no apparent reason. They are electronics fuses - I don't know if they're a delay fuse, but obviously not up to the task.
In an emergency I've used a standard 20-amp automotive fuses, and they'll still blow before something burns up, but they usually melt under the metal cap just from the heat of normal draw from the motor running.

We got rid of the fuses years ago on the vac’s and put in Mercury relays http://www.kleen-ritecorp.com/p-50-mercury-relays-24v.aspx to isolate the motors from the timer, we have replaced a burned out timer since. Another thing you can also do is to install circuit breakers in place of the fuses. These work well http://www.kleen-ritecorp.com/p-3557-10-amp-resettable-breaker.aspx
