Do any of you guys do jobs in all EMT with no MC except of lighting whips?

The vast majority of my commercial work is done that way- pipe only, unless absolutely necessary.

Residential & comercial.
We do RMC also. We use flex for fishing in walls too.

Same area as Tom, same story. One town doesn't even allow whips, or flex for fishing.

We are the only crew in the company that uses all pipe. All other crews and companies down here all use MC

While most of the jobs in the KC area are speced out to be EMT, most are "value engineered" to MC. The major exception is hospital work.

In the same turf and Tom & Dave.

In Chicago, as well as most of the northern suburbs (and many west and south I believe) EMT is the "accepted standard" for most AHJ's. NM and "smurf tubing" (ENT) are prohibited in most municipalities, but many county building depts. consider them OK for resi use in unicorporated areas. Even RNC is frowned upon for anywhere but underground applications (resi) in many towns.

MC is often classified the same way as Greenfield / FMC, and only allowed for flexibility (motor / lighting whips) or for fished applications.

AC (BX) has become less than desirable as well in many towns.

In MA the accepted norm is MC. It depends on the location of course, but 90% of commercial buildings in this area have MC weaved throughout. You can tell a real quality job when it's in pipe or the MC is actually "installed" and not thrown in like loose rope. I have opened suspended ceiling tiles in new buildings and had 25lbs of MC nearly knock me off the ladder!

The company I work for uses EMT to the main J-Boxes and then whips out with MCC. In the walls we mostly use MCC unless its 3-way lighting or something special. Everything is strapped per code and we try to do nice clean runs with the MC. As a courtesy to the next guy, all our MC is at least 12" above the grid.

In office and warehouse buildings, we usually run EMT across the ceilings and use AC (BX) for lighting whips and power into the walls.

The exception is if they have spec'd otherwise, or have oddities like isolated ground and/or upsized/dedicated neutrals.
