I know that the NEC has required a 20Amp Laundry circuit since at least 1975 (that's the oldest code book I have). I find a lot of older homes with the Laundry circuit wired to the small appliance branch circuit. I am wondering if this was ever legal. Based on the age of the homes I have see I am betting this change was made in the late 60s-early 70s?
My own home (1955) was all wired in BX/AC cable. I have both types, some with the aluminum bonding wire and some without. I have herd that the BX without the bonding wire was done away with when the change was made to require grounding type receptacles. When did this take place....I am guessing late 50-early 60s?
I know the BX without the bonding wire around here is sometimes referred to as "rat proof romex" and it provides a poor ground (high resistance/may not trip a breaker etc). But have seen plenty of jobs with 3 wire receptacles wired to it with a bonding jumper to the box.
I have never seen a code book that describes or differentiates between these two types of BX/AC cables.......but have seen plenty of talk and opinions. Anyone have any input on that
