## What is the OD of 1.5 EMT?

Electrical Metallic Tubing (EMT) – Thinwall Conduit

Conduit Trade Size | Outside Diameter | |
---|---|---|

(in) | (mm) | (in) |

1 | 27 | 1.163 |

1 1/4 | 35 | 1.510 |

1 1/2 | 41 | 1.740 |

## Is conduit measured by ID or OD?

Tubing is measured by **the OUTSIDE DIAMETER (O.D.)**, specified in inches (e.g., 1.250) or fraction of an inch (eg. 1-1/4″).

## What is the OD on 1 2 EMT?

ACTUAL OUTER DIAMETER

THIN WALL INCH SIZE (E.M.T.) | ACTUAL OUTSIDE DIAMETER | |
---|---|---|

1/2″ | = | .706″ |

3/4″ | = | .922″ |

1″ | = | 1.163″ |

1 1/4″ | = | 1.503″ |

## What is the diameter of electrical conduit?

A conduit trade size of 1 inch has an actual inner diameter of **1.049 inches**. 2-inch lengths typically have an inside diameter of 2.067 inches.

## How thick is EMT conduit?

---|---|---|

¾ | 21 | 0.049 |

1 | 27 | 0.057 |

1¼ | 35 | 0.065 |

## Will 1/2 inch EMT fit inside 3/4 EMT?

You can fit a **1/2″ into 3/4″ or 3/4″ into 1″ etc**. Just use a torch to evenly heat the last inch or two of the larger pipe. When it is soft enough, twist and push the smaller pipe into the larger.

## How do you measure a conduit pipe?

On the conduit, **measure from the free end to be bent up the calculated number and mark the conduit**. As an example, to bend 3/4” EMT conduit have a free end height of 8.5”, the table indicates to subtract 6” from the 8.5” which leave 2.5” from the end to bend up to make the mark.

## How do you measure electrical conduit size?

Calculate the total diameter of the wires to determine the diameter of the conduit when placing wires of different gauge and type inside the conduit. Find the wire diameter in table 5 for each gauge wire and type. **Multiply the number** of wires for each gauge and type by the wire diameter. Total the results.
