WARNING 

Transformers use conventional transformer oil or 

Envirotemp™ FR3™ fluid for an insulating liquid. 

When the insulating liquid temperature is less than 

-20 °C (-4 °F) for conventional transformer oil or less 

than -10 °C (14 °F) for Envirotemp™ FR3™ fluid, the 

increase in fluid viscosity may reduce make and 

break capabilities of loadbreak devices. Below these 

temperatures, under-oil loadbreak accessories should 

not be used to 

make 

or 

break

 a 

load

. Instead, 

de-energize transformer from a remote upstream 

source before operating under-oil loadbreak devices. 

Failure to follow this warning could result in equipment 

damage, severe injury, or death.

WARNING 

Hazardous voltage. 

 

Do not operate loadbreak equipment if a fault 

condition is suspected. Doing so can cause an 

explosion or fire.

 

Use a hotstick to operate transformer loadbreak 

equipment.

 

After operating transformer loadbreak equipment, 

check that voltages at transformer terminals are 

the expected values. Checking voltages verifies that 

loadbreak equipment operated properly and the 

electrical circuit conditions are as expected.

 

Before servicing transformer secondary connected 

equipment, verify that all transformer secondary 

terminals have zero voltage and ground the 

transformer secondary terminals following industry 

accepted safe grounding practices. Grounding 

secondary terminals protects against situations such 

as a standby generator energizing transformer from 

the secondary circuit.

 

Follow industry accepted safety practices. Utilize 

protective clothing and equipment when working 

with loadbreak equipment.

 

These recommendations are in addition to any 

utility, end user, federal, state, local, or municipal 

regulations which may apply.

 

Failure to follow this warning could result in 

component failure, property damage, severe injury, 

or death.
