Sometimes it isn't our choice.

I understand. I is appealing, however, that MCaP cable is the same price as MC. The exstimate you save 5 minutes per box, since you don't have to make up the grounds. I don't know about that long, but it would save time. I don't hold it against a guy that wants to use this stuff, but I prefer a more conservative option when it comes equipment ground continuity.

That seems too much (to me) like a step backwards. Maybe we should quit pulling grounds in EMT now too.

They did a long time ago in NYC. No grounds pulled in any EMT there.

Does that wire require special fittings? I'm assuming internal clamps are fine but what about external fittings..?

They say it has to be a fitting listed for MCaP in the video on that site. They also have a chart on that site of approved internal box clamps. Apparently, not all boxes can use this cable type, or they wouldn't bother to make a chart of one's that you can.
 
I don't think i'm interested in that type of wire... IMO making up grounds dosent slow the process up... your talking what 30 seconds to strip, twist and cap.... I suppose 30 seconds times any large number will add up, but why not just tell the boys to skip coffee break... :)

NYC also used BX,that had no grounding conductor.Quite interesting when retro fitting a circuit that had somewhere a ground screw used as a neutral lead.Lights flickering and sparks flying.Even better when there was a natural gas light that had been retrofitted for electric light and the gas line was still hooked up.Been there several times and don`t want to try that again.
 
As the ad stated it's a huge labor saver. I would use it in a heartbeat over traditional MC unless the spec called for a copper EGC.

I'd think the cost of a copper EGC would far outweigh the labor savings. Thirty seconds at $50 / hr is 4' of #12 THHN. Even at $100 / hr it's a whopping 8'.

Someone said MCap was the same price as MC... anyone actually price this stuff yet?
 
Please be gentle

Please be gentle

This is my first time posting so please be gentle. I think that some are thinking that there is no egc in the cable, but the info on the link said that there is a ground in the cable equivalent to a copper egc. Another thought was that not all receptacle installs require a pigtail to the box. The picture on the page, with the rs cover I dont think would require a pigtail from the receptacle to the box.

Welcome to the Forum. :)

There is an aluminum 10 AWG as the EGC but it does not have to be terminated to anything just like the bonding strip in AC cable.

You can terminate the 10 AWG AL EGC if you want but that takes away the advantage of speed that this product is aiming for.

Most spec grade or better receptacles are UL listed as "self grounding" and are not required to have a grounding conductor installed on any metal box.

This product is not that different from AC cable except it has a plastic wrap and it can be made with many more conductors than AC cable.
 
oops!

oops!

See, this is why I need you to be gentle. At first glance it looked like an rs cover, but then I realized it is a mud ring. However, I think that if the mounting surface of the ring is flush with the surface of the wall and the receptacle yoke makes contact with it then you don't need a jumper. Somebody just slap me (gently) if I'm wrong.
 
They just started using the MC ap/ all pupose on the Hi rises with the proper connectors......as a matter of fact in my other post "window frame as raceway" is where it all started appearing.....
