Really bad. What happens if someone uses a different cable?

How high is the maximum current? Is a C7 cable and connector the right choice?

If you build something for yourself, regulations are a good base, but don't try to follow them to the letter, like the manufacturers do: they try to comply AND spend a minimal amount of money.

Your main concern should be your safety, and common sense and a good understanding of problems are your best friends.

If in doubt, add a supplementary layer of insulation, and/or ask more experimented people on this forum.

If you try to follow too closely the rules, you run the risk of missing some important safety details.

For a home builder, one additional £, $ or € spent on a project is negligible, and it can make a lot of difference safety-wise, so never hesitate.

The connector and cable are right, a C7 cable and a C8 socket. I will include a main fuse then.

Electrical grade silicone are expensive! May I replace with Araldite epoxy resin instead?

I don't really think adding silicone or araldite is going to achieve anything. You would probably be better off just adding another layer of heatshrink over the joint.

Are you concerned with ground loops through the mains earth?
There may be another way to resolve potential problems and retain protective earth

The objective is to completely cover any live conductive part with best insulation. Maybe a coating of adhesive/sealant between the heatshrink and the iec socket?

I mainly uses portable player like smartphone or ipod as the input source for my amplifier so ground loop is not a concern here. The reason I prefer class II is that I am confident in applying perfect insulation to completely seal the hazardous live conductive path which make designing a safe PE connected circuit a bit redundant.
