The Electricity Safety, Quality and Continuity Regulations 2002

The ESQCR regulations section 9 paragraph 4 states that

"The distributor shall not connect his combined neutral and protective conductor to any metalwork in a caravan or boat."

Therefore, The Hook-Up earth must not be connected to the metal chassis of a campervan.

This appears to differ from your recommendations for earthing and I see many people connecting all their earths and 12v negatives to the chassis. What are your views on the above regulation and how should we comply with this legal requirement to avoid fatal shocks?

Greg,

this applies from my point of view for the AC-out. Combining neutral and protective conductor is no problem until you are connected to an external power source. If there is phase and neutral the wrong way, you've got phase on your chassis. Never combine neutral and protective!

@Greg Virgoe

There are example wiring diagrams, they are not law.

The recommendation from Victron is to always follow local regulations.

12v negative using the chassis on car electric installs. It is not quite the same as grounding, so the regs must be referring to AC grounding. Bonding is done in the inverter by a relay so RCDs still work.

It is up to you now to follow regs and not earth the chassis to the chassis.
