Bonding question

[wireday]

Am I ok to start off 4/5 feet LFMC to EMT then back to LFMC…………………………………….

If I understand the question (and the Code).. it will depend on (a) the circuit size and (b) the total length of the LFMC involved, and the size of the LFMC.
250.118(6) will give the details.
The total length of the LFMC can not exceed 6 ft and the circuit would be limited to 2o amps for 1/2" and 60 amps for 3/4 thru 1-1/4

I should have included I am pulling in a GEC not using pipe run for GEC, and LTMC at each end under 6 feet

Be better to run that in pvc and non-metalic liquid tight.

Just to clarify;
GEC Grounding electrode conductor
EGC Equipment grounding conductor.

Which one are you installing?

Ok, I am pulling a green ground inside,I am confused at this point

Is it for a circuit or the "green ground" will end up on a grounding electrode like a ground rod?

Branch circuit

Then an EGC. If the flex is required for flexibility after installation then a wire type EGC is required even if the raceway qualifies as an EGC.

Ok thank you, I dont think I’ve ever had LFMC at each end of EMT run before
