You need a 20A feeding the Spike and a 20A installed in the Spike. It is not an issue of getting caught by your inspectors. It is a safety issue. The Spike is only rated at 20A.

instead of using a bigger CB, investigate why it is tripping. You have a shorted wire or a bad compressor. It needs to be fixed.

It is hard to tell from the posts but it appears the fuse on the Spike is blowing. If you replaced it with a 40 amp fuse and it still blows, you have other issues. There is a short in the compressor or your wiring. Often teams get the compressor wiring under the compressor or wrap it around the "head". Under means the wiring gets clamped during compressor run since the compressor is vibration prone especially if not mounted properly. Around the head, the compressor gets really hot and likely can melt through the wiring.

If you are simply blowing 20 amp fuses in this application then that is normal. The 20 amp fuse in the Spike is guaranteed to blow when running the compressor. Start current is 25 amps while run current is 10-12 amps. Replace with a 20 amp breaker.
