Hello all!
For the first time I am gonna be working with MI cable. The #2 MI cable will be part of a riser that feeds a booster pump for a fire system. The MI cable will run from a pullbox in a basement mechanical/electrical room through a long route to the second floor with plenty of bends and obstructions. From the second floor it changes ober to thhn in a pullbox and from there goes to the roof in conduit enclosed in 2 hour concrete structure.
Our plan is to use a gangload of pulleys at most bend locations and a pulling machine to pull.
We were thinking of supporting PVC elbows at appropriate locations where it would be more feasible than pulleys and pull the MI through the elbow and cut the elbow out after or leave it as a sleeve if poasible. Sound like a good idea?
Would love anybodys input on problems that may arise during the installation or pull of an MI run. Or any suggestions, tips, important things to know about working with MI.
Also if youd like share info about previous installations you were invloved in MI related.
To conclude, I am curious about anything related to MI cable to help me go into this as smooth as possible.
Thanks for reading!
