Clamp Connector (MC Cable)

[hardworker]

Can the Halex Model #20570 3/8" (1/2" KO) Clamp Combination Connector be used with 10-2 w/ground MC cable? I know it fits 12-2 w/ground MC cable, but can not find any literature about 10-2 w/ground.

You would have to know the dimensions of the cable:

Southwire's 10/2 Armorlite MC has an overall diameter of .566", as an example.

I don't have any way to measure that accurately. Will 10-2 w/ground MC cable work with this connector? Please help.

Taking the two previous posts in combination, you have a cable with diameter .566" if it matches the Southwire part, and a clamp that accepts a maximum .547 diameter if the cable is steel clad, smaller if Al.
Please tell me if it will fit? You should not need to measure to do that.

PS: Try wrapping a strip of paper around the cable, measuring it and dividing by 3.14. That should be close enough.
And if you tell me you cannot divide I will have less respect for you.

The connector easily slips over the aluminum clad armor. The 3 conductors pass thru the restricted opening, but they don't have much play. The electrical supply houses in the area say 10-2 w/gd is the maximum, but I don't always trust the guys behind the counter. They don't carry a specific connector for 10-2 w/gd.

Many other competitor's connectors that are basically the same thing will accept the 10-2 so I would think you are likely safe assuming this one will as well. As a general rule if it will fit it is likely acceptable. I think the more important figure is cable diameter, and the actual listings of 10-2, 12-2, etc. are typical examples of cables that likely fit and not necessarily a confirmation that all such types will actually meet the dimensions.

"As a general rule"? That doesn't fly. If the product listing does not state that a 10/2 MC can be used, it cannot be used. Period. End of story. There are other products on the market that are listed for use with a 10/2. Use one of those.

Not true in this case because use is specified by diameter... and already demonstrated as compliant for Southwire's Armorlite 10/2.

It flies for a short time if you toss them out the window because you are disgusted with them:happyyes:
