I suppose that the DNO is concerned that they could later sell your smart EVSE and DIY fit an eBay dumb one. The supply must assume that such illegal activities will occur.You just need an EVSE that supports load curtailment. No need to unloop or have other expensive/disruptive works done.
I can see the viewpoint. However max demand / load curtailment is an install regs rather than dno issue. DNOs dont get involved for electric showers/ovens etcI suppose that the DNO is concerned that they could later sell your smart EVSE and DIY fit an eBay dumb one. The supply must assume that such illegal activities will occur.
But if you, for example just install an EVSE without telling them, and nothing goes wrong, can they do anything ?Here are a couple of quotes from a debate on this subject on the IET (sets the Regs) forums:
"A statute is an Act of Parliament, ie. it is a major piece of legislation requiring consent from both houses of Parliament and requires royal consent to be enacted. Parliament does not have time to make all legislation, so sticks to the big stuff from which delegated legislation can be made by other departments/authorities. In the case of electrical matters, The Health and Safety at Work Act is an 'enabling Act', it sets out a broad spectrum of health and safety ideals from which delegated legislation (such as statutory instruments) are formed.
So although the 17th edition is not statutory (it's not an Act of Parliament), it still has legal standing. Most of the laws in this country are created by delegated legislation eg by-laws are only made by local authorities, but are still legally enforceable. The Electricity at Work Regulations is an example of delegated legislation, again, it's not an Act of Parliament (it's [not] a statutory instrument) but has legal standing. So yep although the 17th edition is not a statute, it is law."
"A piece of legislation does not have to be a statute to be law. The 17th edition could be cited in a court of law as the recognised Code of Practice for sparkies to follow.
Basically, Parliament delegate specialists to make legislation on loads of different subjects ... Parliament just sets out a framework (eg. the Health and Safety at Work Act) from which specialists work from when drafting the finer points. These 'finer points' (such as the 17th edition) are still law, even though Parliament didn't make em."
I'd say that the Regs are 'legally enforceable' in that if anything happens (someone gets killed by a shock) then whoever did the installation could be prosecuted in a court of law, probably under a Health and Safety Act. So they do have legal force. To be specify, non-qualified people are only allowed to do a few specific things to the electrical installation in their homes (you could do more and then get it inspected). If you do more then you are liable for any subsequent effects, and I assume your insurers could refuse to pay out if the house burnt down. The Highway Code is just the same - it's not a statutory instrument but is legally enforceable.
A guy in our village was telling me about his new PHEV Prius that came with a PodPoint home charger. He was annoyed when they called to fit it when they refused that day as his house, unknown to him, was on 3 phase. He proudly went on to describe how he insisted on them removing the 3 phase and putting him onto normal domestic supply.I see being unlooped for free the same as having a skinny lead water pipe replaced for free - just do it before it stops being free.
Well, if they don't find out, then they won't do anything. But if they do find out then they can always cut off the supply, which is definitely doing something.But if you, for example just install an EVSE without telling them, and nothing goes wrong, can they do anything ?
Application for Install in looped supply not submitted, installing at property with high max demand and a 60amp bullet....In what circumstances was this ?
And if you don't..?
Just curious.. I'm not worried, all I've installed is a 32A Commando socket...
Agreed, but you have to take the worst case scenario as your usage might fit one profile but a subsequent owner a different one. Before EVs most house supplies had significant capacity reserves but this, and the grid in general, is being significantly challenged. It'll be interesting to see if we end up with charge points being limited dynamically by DNOs, or whether the market model as exemplified by Agile is sufficient to manage the situation.The current (see what I did there) diversity calcs for the house itself are a wild guess unless time and effort is spent with the household understanding their use.
We already do this with every install for exactly this reason. We have even triggered supply upgrades with data we collect from Smart Chargers.It would simplify things if load limiting was made compulsory and part of the sign off process but with some form of reporting so the unit(s) provide feedback on the real available current for EV use (as we move to two or more per household).
This could them be used to justify a fuse upgrade or whatever is needed to unlock more.
perfect case. The shower load would vary wildly with the seasons too.We already do this with every install for exactly this reason. We have even triggered supply upgrades with data we collect from Smart Chargers.
What you typically find is that the usage patterns make it fine (charge middle of night with nothing else on). But there are some odd patterns or setups that mean everything goes on at once. Two chargers is the other biggy.
One example we had was a nightshift worker who got home about 7am. Plugged in, hit boost, had a shower and put the washing machine on meaning we were hitting 80A and derating the charger pretty much every day.
