i wanna ask something, it just acrossed in my mind.
we have two generators type 3412, and both serial number PTGC 00745 and ATGC 00624.
last 5 digits mean product sequence number.
"TGC" letter mean the type (i guess cause i'm not sure)
but "P" and "A"?
is it a letter for grade of generator? i don't know
would you like to explain it to me.
it's just always bugging me. :)
