Splices and terminals wrapper

Why you care (60 seconds)

Connections and splices are common failure points. Proper terminations prevent heat damage, loose conductors, and inspection failures.

Where people lose time

  • Making splices outside of approved enclosures.
  • Using connectors that are not rated for the conductor material.
  • Skipping torque requirements or using the wrong tool.

This is

The rule in plain language

Splices and terminations must be made in approved enclosures and with connectors that match the conductor and equipment ratings.

When it applies

Any time conductors are spliced, tapped, or terminated on equipment.

What you must do (checklist)

  • Make splices in approved boxes or fittings with covers.
  • Use connectors listed for the conductor material and size.
  • Follow equipment termination ratings and torque values.
  • Maintain grounded conductor continuity where required.

Quick examples

  • Use listed connectors for aluminum conductors when specified.
  • Keep splices accessible rather than buried behind finishes.

This is not

Common misreads

  • Assuming any wire connector works for any conductor material.
  • Treating a device box as optional for splices in finished spaces.

What it doesn't cover

  • Pull box sizing or raceway fill calculations.
  • Special equipment rules for motors or HVAC.

False friends

  • A tight-looking splice is not acceptable if it lacks a listed connector.

Exceptions & edge cases

  • Some splices are allowed inside equipment where permitted and listed.
  • Certain conductor types require special termination practices.

Cross-references (NEC map)

  • Primary: 110.14, 300.15
  • Secondary: 300.13

Exam traps

  • Forgetting the need for a box at a splice location.
  • Selecting a connector without matching conductor material.

Field notes

  • Use a torque screwdriver to document compliant terminations.
  • Keep a small kit of listed connectors for mixed conductor materials.
