TAKE IT FOR A TEST DRIVE

Three questions. No sign-up.

01 / General requirements

A listed panelboard is supplied with a torque value for its terminals. Which installation practice satisfies the terminal tightening requirement?

  1. Use an approved means to achieve the indicated terminal torque
  2. Use a torque value selected only from conductor ampacity
  3. Apply the same torque used for the breaker handle
  4. Tighten until the conductor insulation deforms
Show answer & explanation

Use an approved means to achieve the indicated terminal torque

Achieve the tightening torque indicated on the equipment or in its installation instructions using an approved means. A calibrated torque tool is one such means; follow any applicable manufacturer instructions.

03 / General requirements

A 120/240 V panel faces a concrete wall in a typical installation. For working-space depth, how is the concrete wall treated?

  1. As an open doorway
  2. As an insulated surface
  3. As a grounded surface
  4. As an exposed energized surface
Show answer & explanation

As a grounded surface

Concrete, brick, and tile walls are treated as grounded for the working-space table. At 150 V to ground or less, the minimum depth is 3 feet in all three conditions.
