Danger, Danger, High Voltage!

Although it annoys me that mechanics consider even 400V "high" voltage. HV is supposed to be 1,000V, minimum.

400V is dangerous though. The traditional 12V is not.

Absolutely, but 400V isn't as dangerous as 1,000V. IEC standards have already established all of this, above 1,000V is HV, below 50V is ELV and generally safe. Automotives have come in and labelled anything above like 24V as "HV", which is just silly.
