EMT connectors/compact conductors
Getting close to finalizing relocation of panel board. Using 1 1/4" emt from disconnect to board-both indoors. Planned on using compression couplings, but have also seen the set screw type in both steel and cast material.
Q-Any reason for the different material other then maybe manufacturing processes and/or costs?
Q-Any real world preference, reasons, application, between the set screw or compression? -- I am pulling a separate eqpt. Ground between the disconnect & board.
Compact conductors-THese are referred in Table C.1(A) in the NEC and a definition given, but I have never seen these mentioned as being used.
Q-Are service entrance conductors normally of the non-compact type?
Q-Is the compact more related to specific applications?
