ADJUSTMENT FACTORS
310.15 exception #5: Adjustment factors shall not apply to Type AC cable or to type MC cable without an overall outer jacket under the following conditions:
(a) each cable has not more than three current carrying conductors.
(b) conductors are #12
c) not more than 20 current carrying conductors are bundled, stacked or supported on ?bridle rings?
What is MC without an overall jacket?
Is this the typical MC I get when I ask for MC at a supply house?
I use a lot of MC and I?ve always kept my bundles to 9 current carrying to avoid the 50% adjustment factor required by 310.15B2a.
If this applies to the MC I use on a regular basis, this would save me a boat load of headaches.
