BASIC ELECTRICAL PRACTICES LAB RESIDENTIAL WIRING

BASIC ELECTRIC PRACTICES LAB 1 PHASE

THE IMAGE HAS THE CONNECTION OF THREE PHASE

SINGLE PHASE CONNECTION:

• Phase -voltmeter positive
• voltmeter positive - Ammeter positive
• Voltmeter negative -PF meter input neutral
• Ammeter negative -PF meter input phase
• PF meter output phase - Single phase energy meter input phase
• PF meter output Neutral - Single phase energy meter input  neutral
• Single phase energy meter output phase-Resistive load phase
• Single phase energy meter output  neutral - Resistive load neutral

Apparatus of single and three phase energy meter will be similar.
