Re: Compressor blowing spike fuses or melting spikes

This compressor uses a "wobble" technology in that the piston and rod are one piece so that the piston head actually wobbles as it is moved by the crank. The seal is flexible and so the piston to wall clearance is fairly big (i.e. on the order of hundredths as opposed to thousandths of an inch.)

A 30 amp fuse violates the wiring rule and IFI requirements for the Spike, sorry.
