These
electrical energy source labels identify disconnect locations using a red lightning-bolt symbol and a matching E-number. Use the identifiers to correspond with the electrical isolation points documented in your equipment's energy control procedure.
Printed identification
E-[selected number or custom identifier]
The design has a red lightning bolt, red identifier and rounded red border on white. Standard selections run from E-1 through E-40.
Product details
- Size: 3 inches wide × 1½ inches tall.
- Adhesive identification stickers, not hanging tags.
- Select a number from 1–40 or choose the custom option.
- The number option identifies the printed source number, not a pack containing every number.
Custom source numbering
Choose the custom Text option and enter the exact identifiers required in the
Notes section when checking out. Examples include E-99, E-1-1 and E-A-1. State the full identifier you want printed to avoid ambiguity.
The custom image's E-? is an example placeholder. Its blue arrow and ADD YOUR SOURCE NUMBER HERE caption explain customization; they are not part of the printed sticker. Custom identifiers are printed for your order, not supplied as blank write-in fields.
Recommended placement
Place each sticker on a suitable fixed surface at or beside the corresponding electrical disconnect, visible to personnel identifying that isolation point. Match the identifier to the correct equipment procedure and avoid covering switch positions, equipment identification, ratings or hazard warnings.
This is general placement guidance, not a verified mounting location for a particular machine or panel. Have the person responsible for the equipment's energy control procedure confirm the identifier and position. Apply to a suitable clean, dry surface.
Identification, not isolation
These labels identify electrical energy sources; they do not lock a disconnect, indicate whether it is energized or verify that energy has been isolated. They are not personal lockout tags and do not replace equipment-specific energy control procedures, locks, testing or other required hazard information.
A numbered sticker alone does not establish compliance or make equipment safe to service.
