Can i use BX cable as a EGC ????????????????????????????????????????????????????????????????????????????????????
Can you be specific about the type of cable you are talking about?Can i use BX cable as a EGC ????????????????????????????????????????????????????????????????????????????????????
I second that.Can you be specific about the type of cable you are talking about?
But if the OP is actually looking at MC it is not a listed EGC. Using "BX" as a cable type in modern times raises electrofelon's question.If it's a listed AC then the outer jacket/armor is a listed EGC.
Yeah, around here everyone calls AC BX but who knows exactly what the OP is referring to. I'm assuming it's AC.But if the OP is actually looking at MC it is not a listed EGC. Using "BX" as a cable type in modern times raises electrofelon's question.
It is used extensively in NYC.Why does AC even exist any more?
I really like it. I find the green wire in MC to be a horrendous waste of material and results in a big increase in labor.Why does AC even exist any more?
I haven't used AC in NYC in at least 10 years. It's all MC now. You might see AC health care facility cable in hospitals. When we want to save money we use MC-ap so no EGC's to contend with.It is used extensively in NYC.
So why did they come out with MC-ap? Why would someone use that over AC? What is the difference? (I know it has a bigger bond wire, but in practice and price what is the difference. do we need both?)I haven't used AC in NYC in at least 10 years. It's all MC now.

Steel AC has a much stronger, thicker jacket and is therefore much heavier than it's lightweight MC counterpart. MC doesn't have paper on each conductor so terminations are somewhat faster. It's also easier (faster) to strip long sections of jacket like when entering a panel.So why did they come out with MC-ap? Why would someone use that over AC? What is the difference?

So does anyone make aluminum jacketed AC cable? I checked UL Standard 4, and per the scope, it's an option under the standard.Steel AC has a much stronger, thicker jacket and is therefore much heavier than it's lightweight MC counterpart.
I was just about to ask if AC could be aluminum jacketed.So does anyone make aluminum jacketed AC cable? I checked UL Standard 4, and per the scope, it's an option under the standard.

ok, one of the guys that was on Mike's 2020 code change videos was from NYC and said that is all they used. No actual experience with what they use out there.I haven't used AC in NYC in at least 10 years. It's all MC now. You might see AC health care facility cable in hospitals.

AC lite.I was just about to ask if AC could be aluminum jacketed.
I thought you were joking at first but I googled it and it does come upAC lite.

In majority of the specifications we see they specify that they want the wire type green EGC. We often submit MC-ap to see if they will accept it because it saves a huge amount of labor not having to terminate the green wires. This is similar to specifications that call for wire type EGC's in EMT.Why does regular MC seem to be vastly more popular than either mcap or type AC? I suspect it is because of the cult of the green wire and the vast majority of electricians have been programmed to want the wire EGC?
