Re: <R55> relay 20A

Holty et al,
The 20 amp breaker that must feed each Spike is in place to protect the wiring that runs to the Spike. Should that wire short, the breaker trips to protect the wire from self destruction. The 20 amp fuse on the Spike itself is to protect the contacts of the relays inside the Spike from destruction. The fuse on the Spike that feeds the compressor may be changed to a 20 amp self resetting breaker as shown in the rules quoted above. The compressor has a start current of 25 amps while it only has a run current of 10.5 amps. If you don't change the fuse to a breaker, you will most definetly be changing the fuse often. Remember this rule only applies to the compressor Spike and no others.
