Sidepod my old friend...
(and I'm not sure you're even right or that the cable in question does not meet the regs - a 16 amp rating will I'm sure allow for a significant safety margin overload well above this nominal figure)
...have you ever thought of posting in a manner of the friendly nature of this forum rather than being a sarcastic old ***?
When was the last time you fed anything
approaching a whopping 16 amps into your Cali???!
As pointed out above by me and others you'll be lucky to get more than 6 amps on any campsite and many in France it's more like 4 amps max. The trips on either the site electrics or the Cali would go pop - been there done it with a dodgy 1000w ie 4amp low wattage fan heater at midnight on a busy French site - boy were we popular when we blew the site supply and the whole campsite was plunged into darkness!
