EMT Conduit
Thin-wall metal tubing that carries wiring in most building interiors.
Quick Answer
EMT, electrical metallic tubing, is a thin-wall metal raceway for wiring, commonly used in exposed and concealed interior locations. It is taken off in linear feet by trade size, usually in 10 ft sticks, with couplings, connectors, straps and boxes counted separately in EA.
The Full Picture
EMT is the standard interior raceway on many commercial jobs. It is lighter and cheaper to install than rigid conduit because the wall is thin and the fittings are not threaded, so it is bent in the field and joined with compression or set-screw couplings and connectors. It is a raceway in the sense of an enclosed channel designed expressly for holding wires, cables or busbars, and the code, not this page, sets where it is permitted.
On the documents EMT is rarely labeled run by run. Plans show conduit as line work with hash marks, and the spec section for raceways sets EMT as the default or restricts it, for instance requiring rigid metal conduit in exposed or damage-prone areas or underground, and a minimum trade size. General notes may state a minimum size such as 3/4 in for home runs. The estimator therefore sets the conduit type for each area from the spec, and then sizes each run from the conductor count and size.
The takeoff unit is the linear foot, sorted by trade size. Typical sizes run from 1/2 in up to 4 in, and each size has its own price per foot and its own fittings. Because EMT is commonly sold in 10 ft lengths, the order is rounded up to whole sticks. Fittings are counted EA per size: couplings between sticks, connectors at boxes and equipment, and straps or hangers at the support spacing the estimator assumes. Offsets, bends and kicks are added where the plan or section shows them.
Pricing pitfalls include sizing every run at the minimum when the conductor count needs a larger size, leaving the fittings out because they are not drawn, and overlooking EMT's limits: where the spec requires rigid or flexible conduit for the last stretch to equipment, those sections are priced separately. Runs that stack several conduits on trapeze hangers carry hanger quantities as well.
Real Examples
Common Misconceptions
People assume: EMT can be used anywhere conduit is needed.
Actually: Permitted locations are set by the code and the spec. Exposed, underground and some hazardous or damage-prone areas call for other raceway types, so the estimator checks the spec by area.
People assume: The conduit LF on the plan is the EMT order quantity.
Actually: Plan lengths leave out rises, offsets and waste, and the purchase is in whole sticks. Fittings and supports are counted on top.
Does MeltPlan Solve This?
Partially — adjacentEMT lengths by trade size and the fitting counts are measured from electrical plans, and MeltPlan's takeoff service covers that measuring: AI pulls quantities from the plans, and US-based experienced estimators review and adjust them. The raceway type for each area, bends, offsets and waste allowances stay with your estimator.

What does EMT stand for?
EMT stands for electrical metallic tubing. It is a thin-wall metal raceway that protects and routes electrical wiring, and it is often called thin-wall conduit.
How is EMT conduit measured for a takeoff?
It is measured in linear feet by trade size and ordered in whole sticks, commonly 10 ft. Couplings, connectors, straps and boxes are counted EA.
What is the difference between EMT and rigid conduit?
EMT has a thinner wall and unthreaded fittings, which makes it faster to install indoors. Rigid conduit is heavier and used where more protection is needed. The spec decides which applies.
Where is EMT shown on the electrical drawings?
It is usually not labeled individually. Plans show raceway as line work, the spec section names the permitted type, and a general note may give minimum sizes.
