The Time to Install EMT Conduit calculator estimates the amount of time needed to install Electrical Metallic Tubing (EMT Conduit) based on the length of the conduit (L), the Level of Difficulty (lvl) and the size (S) of the conduit.
INSTRUCTIONS: Choose units and enter the following:
- (S) Size of Conduit in Inches (choose: 1/2", 3/4", 1", 1-1/4",1-1/2", 2" , 2-1/2" , 3" , 3-1/2", 4" )
- (lvl) Level of Difficulty.
- (L) Length of the Conduit Run
EMT Conduit Install Time (t): The calculator returns the install time in hours, and the weight in pounds. However these can be automatically converted to compatible units via the pull-down menu.
The Math / Science
EMT stands for Electrical Metallic Tubing (aka thin-wall tubing). EMT is often used as a lower cost solution to galvanized rigid conduit (GRC). EMT is not threaded but can be used with threaded fittings via the use of clamps. EMT is typically made of steel.
The relationship between length of conduit, level of difficulty, size of EMT and the time to install comes from industry standard numbers. The following table is the basis of this calculator.
| Size | Lvl1 | Lvl2 | Lvl3 | Lvl4 |
|---|---|---|---|---|
| 1/2" | 0.030 | 0.037 | 0.045 | 0.053 |
| 3/4" | 0.040 | 0.050 | 0.060 | 0.075 |
| 1" | 0.050 | 0.062 | 0.075 | 0.094 |
| 1-1/4" | 0.053 | 0.056 | 0.079 | 0.099 |
| 1-1/2" | 0.056 | 0.070 | 0.084 | 0.105 |
| 2" | 0.064 | 0.080 | 0.096 | 0.120 |
| 2-1/2" | 0.070 | 0.087 | 0.105 | 0.132 |
| 3" | 0.080 | 0.100 | 0.120 | 0.150 |
| 3-1/2" | 0.100 | 0.125 | 0.150 | 0.188 |
| 4" | 0.120 | 0.150 | 0.180 | 0.225 |
