6.2 Load Break Oil-Immersed Rotary Switches (LBOR)

WARNING: Do not operate load break equipment if a fault condition is suspected. Doing so can cause
an explosion or fire.
WARNING: Use a hotstick to operate transformer load break equipment.
WARNING: After operating transformer load break equipment, check that voltages at transformer
terminals are the expected values. Checking voltages verifies that load break equipment operated
properly and that electrical circuit conditions are as expected.
WARNING: Before servicing transformer secondary connected equipment, verify that all transformer
secondaryterminalshavezerovoltage andgroundthetransformersecondaryterminalsfollowing
industry accepted safe grounding practices. Grounding secondary terminals protects against situations
such as a standby generator energizing transformer from the secondary circuit.

Two-Position LBOR Switch

The Two-Position LBOR Switches (Fig. 15) are provided optionally in padmount transformers to achieve load
breaking or making and loop feed switching. LBOR's will have a hotstick operable handle

The spring-loaded activating mechanism of the switch ensures quick load break or load make operations in
less than one cycle, and should be performed with a hotstick
