wiring from central (regulated) suppliers on a common scheme began in the US in/around 1911, with major cities joining in the grid through the next t en years or so. Rural Electrification began in earnest in 1936 and by 1940, the 'grid' was available to the entire US.
common people in GB until starting in 1926, making GB about 15 years behind the US, and much slower on the uptake moving forward. Pretty much everythi ng done in the US was brand-new for the first 15 years or so - and the rest of the world learned from it.
The unified electrical standard didn't complete here until about 1960. It w as a slow business.
ded (both the house and the wiring) in 1928. In 2005, the main service was upgraded and grounded wiring extended throughout the house to all branch-ci rcuits and GFCI devices installed in all 'wet' locations - must have cost a fortune!
1928 wiring in 2005 would be unthinkable here. Haven't seen anything that o ld since one exceptional commercial property in the 80s. It was an instant inspection condemnation.o - are fine if they can be screwed down as a terminal strip (and they are approved in that application. But as individual joints, they are quite dang erous.
I'm not buying it at all. We use them all the time.
ection than a single screw bearing on two conductors in a small opening. Tw ist together first (good mechanical connection), cut square or on a very sl ight angle, then install the correctly sized wire-nut, very tight. I have d one (easily) tens of thousands, and I carried at least five different sizes on any given job. Were signal-wiring involved, that would be four more siz es.
They were banned here in '55, but I lack further info on that.
