customer has a 200a meter loop and service on H frame. the h frame is lit up with a barnyard light. the light is tapped off the 200a disconnect with #12 with 20a inline fuse. Is this considered a 10' tap rule for the light?? basically is this allowed.

Not sure about the meter loop and H frame but it is permissible to tap a #12 to a 200 amp feeder if the tap conductors are 10' or less. If the tap falls under 240.21(B)(5) then there is no length limitation.

meter loop/disconnect sit on an h frame. The service feeds a shelter about 30' away. the H frame is lighted up with barn yard light. The #12 is tapped off the load side of the disconnect. i was just asking was this allowed. Thanks for info

The inline fuse assembly must be listed as a branch circuit overcurrent protective device for this application.

Is this used for lights only or can this tap be for any device that is fused?

the tap conductors end at the OCPD. Beyond that point it is just a regular branch circuit and can be used as you see fit as long as it meets code requirements for a branch circuit.

somewhat pickey but in all probability the lug on the 200 amp breaker is not designed for the #12.
A fair number of circuit breakers have either a tapped hole in the lug for control circuits or you can get a lug that will fit smaller wires for it.

IME it is pretty common for people to drill and tap MCCB lugs for small wires but I have never allowed that.
