EETC Conduit & Raceway Systems 2

Question 1

When making a 90° stub-up bend with a hand conduit bender, the term 'deduction' or 'take-up' refers to:

Accepted Answer

The amount subtracted from the desired stub height to mark the bend point

Answer

The total length of conduit consumed by the bend

Answer

The stub height measured after the bend is formed

Answer

The radius of curvature formed by the bender shoe

Question 2

An 'offset bend' in conduit is used to:

Accepted Answer

Shift the conduit parallel to itself to clear an obstacle such as a beam

Answer

Make a 90° turn around a structural corner

Answer

Join two pieces of conduit end-to-end without a coupling

Answer

Create a bend angle greater than 90°

Question 3

The 'gain' (or 'shrinkage savings') in conduit bending refers to:

Accepted Answer

The length saved because conduit travels diagonally through the curve rather than in a right-angle path

Answer

Additional conduit length required to complete the bend

Answer

The amount of conduit material wasted during the cutting process

Answer

The increased wall thickness created by bending

Question 4

When installing EMT into an enclosure located in a wet location, the NEC requires:

Accepted Answer

Compression-type fittings listed and marked for wet or rain-tight use

Answer

Set-screw type fittings sealed with thread compound

Answer

Push-in type fittings with neoprene gaskets

Answer

Any standard fitting covered with electrical tape

Question 5

The maximum spacing between conduit supports for 3/4-inch EMT installed in a horizontal run is:

Accepted Answer

10 feet

Answer

6 feet

Answer

8 feet

Answer

12 feet

Question 6

When field-bending PVC conduit, the approved method is to:

Accepted Answer

Apply heat with a heat gun or oven until pliable, then form the bend by hand

Answer

Use a standard metal hand bender with conduit shoes

Answer

Cold-bend the conduit over a mandrel without heating

Answer

Use a hydraulic bender the same way as for metallic conduit

Question 7

A 'saddle bend' (four-bend saddle) in conduit is used to:

Accepted Answer

Pass the conduit over a pipe or obstruction while returning to the original plane

Answer

Make a single 90° direction change

Answer

Connect conduit to a junction box at a 45° angle

Answer

Secure the conduit to a structural member
