Finally got my ASHP quote through (for an Ecodan R32 and not Vaillant as originally assumed) and one of the forms I need to fill (for DNO approval I believe) is the declared voltage at connection. What is that?
I monitor my voltage every 10s and it peaks around a maximum of 246V (on the CU side of my Optivolt 100 using the 4% tap - the DNO wasn't interested in addressing it bouncing around 253V).
Suggestions?

Re: Declared voltage at connection
I guess they want to know if the voltage is on the low side so they can think about tapping the transformer to pro it up.

(Artist formally known as ******, well it should be obvious enough to those for whom such things are important.)

Re: Declared voltage at connection
A bit late but I think the "declared voltage" is 230V (as opposed to 380V 3 phase).
Don't think the DNO will be bothered/do anything about the actual voltage. It is in spec if it does not exceed 253. Mine is regularly >245 cos I am near the s/station and incandescent bulbs have a short life, not that I have many left in use.
