Right, this was an interesting one, thanks for bringing this up. Had to hit the books and read some forums to wrap my head around it, but fair play, I learned something new.

I've deployed a patch that will take into consideration the earthing type and only tick item 4.13 of the checklist on page 4 of the EICR only if TT earthing is checked on Step 3, Part 7 under the "System Configuration & Earthing". For every other type of earthing system it will mark it as N/A.

Thanks for bringing this up.

Will need to do a deep dive on this one to educate myself a bit about the topic as I never worked with TT, implementation wise is quite easy.
