Circuit directory check
Type a panel's directory as the card reads today, one circuit a line. The check lists the circuits to describe better.
Result
11 circuits read · 4 to fix
- Circuit 4 is in use but has no description.A breaker in use needs a description of what it feeds. Spare breakers are listed as spare.
- Circuits 6 and 11 read the same.Two circuits that read the same cannot be told apart. Add what distinguishes them.
- Circuit 7: "Lights" alone does not say which circuit it is.A word alone such as "Lights" or "Misc" does not say which circuit it is. Say what and where: "Lights, sales floor north".
- Circuit 9: "Mike's office" depends on who uses the room.A description that depends on who uses a room ("Mike's office", "temp") goes out of date. Use the room number or its use.
What the check looks for
Every circuit described
A breaker in use needs a description of what it feeds. Spare breakers are listed as spare.
Clear and specific
A word alone such as "Lights" or "Misc" does not say which circuit it is. Say what and where: "Lights, sales floor north".
Different from all others
Two circuits that read the same cannot be told apart. Add what distinguishes them.
Not tied to who is there
A description that depends on who uses a room ("Mike's office", "temp") goes out of date. Use the room number or its use.
Positions that fit
A 2-pole breaker takes two positions on one side (1 and 3), a 3-pole three. The positions must not overlap and must fit the panel.
Based on the circuit directory wording of NEC 408.4(A) (2020 edition text): every circuit and circuit modification legibly identified as to its clear, evident and specific purpose or use, in a degree of detail the inspector approves, with spare positions described, and no description that depends on transient conditions of occupancy.
