Look inside this book This portable field booklet defines essential safety checks that determine if sockets are correctly wired, or if corrections must be made before setting meters.
Each socket check is clearly described using computer-precise illustrations and step-by-step procedures.
All checks use only a basic voltmeter, set at just one voltage range. No resistance measurements are required. Some checks use a temporary jumper.
Covers all popular single- and three-phase services and sockets:
- Single-phase, two-wire
- Single-phase, three-wire
- Three-wire network
- Three-phase, three-wire delta
- Three-phase, four-wire delta
- Three-phase, four-wire wye
Printed on heavy coated card stock, for years of outdoor use.
For all linemen who make socket checks, and a handy field reference for metermen.
