I kind of doubt it was ever a standard size. I could see some sort of OEM version being produced for some specific equipment that someone happened to have ready access to though.THW AL gives some idea of the probable age of the install but, curious, was 55 amp ever a "standard size" ?
Seemingly someone went out of their way to use such.
