Sorry for being thick but could one of the older guys enlighten me as to what size roughly in metric 19.052 is and also 7.029
Found this hand written user guidance next to an old consumer unit the other day.

I was thinking more copied down by a diyer from a handbook. If it was being dictated you can imagine 30 being mistaken for 13 too.I think they were done by an apprentice, too.
Looking at the first photo...….never come across 13 amp fuse wire.
Hmm, I wonder whether I'm supposed to count myself in that category or not?could one of the older guys enlighten me as to what size roughly in metric 19.052 is and also 7.029
If you PM me an address and I’ll post it out to you.....I’ve got a few stamps.Hmm, I wonder whether I'm supposed to count myself in that category or not?
For the benefit of the younger guys, those cables sizes are not quite written correctly on the schedule; they should be 7/.029 and 19/.052, meaning seven strands of 0.029 inches diameter etc. The quickest way to convert to metric is to multiply 507 by the number of strands and by the square of the diameter.
507 x 7 x (0.029)² = 3.0mm²
507 x 19 x (0.052)² = 26mm²
Also, guys of all ages, we need stuff like this for the museum. Anyone finding old paperwork from electrical contractors, drawings, schedules, invoices etc please let me know if you don't want it.
Haha.....West Wing!Did you nick that from the White House?
How many ways is it? I might come across some more.Fantastic! Thank you, address follows. I think we've got a fuseboard with Grierson's label on the front but not 12-way unfortunately, so we can't pretend the schedule goes with it.
