Replacement Circuit Breaker

SECTION 2: SAFE PRACTICES

VR-Series breakers are equipped with high speed, high energy

operating mechanisms. They are designed with several built-in

interlocks and safety features to provide safe and proper operating

sequences.

WARNING

TO PROTECT THE PERSONNEL ASSOCIATED WITH INSTALLATION,

OPERATION, AND MAINTENANCE OF THESE BREAKERS, THE FOLLOWING

PRACTICES MUST BE FOLLOWED:

•

Only qualifitd ptrsons, as dtfintd in tht National Eltctrical

Saftty Codt, who art familiar with tht installation and

mainttnanct of mtdium voltagt circuits and tquipmtnt,

should bt ptrmitttd to work on thtst brtaktrs.

•

Rtad thtst instructions cartfully btfort atttmpting any

installation, optration or mainttnanct of thtst brtaktrs.

•

Always rtmovt tht brtaktr from tht tnclosurt btfort

ptrforming any mainttnanct. Failurt to do so could rtsult

in tltctrical shock ltading to dtath, stvtrt ptrsonntl injury

and/or proptrty damagt.

•

Do not work on a brtaktr with tht stcondary ttst coupltr

tngagtd. Failurt to disconntct tht ttst coupltr could rtsult

or proptrty damagt.

•

Do not work on a clostd brtaktr or a brtaktr with closing

springs chargtd. Tht closing spring should bt dischargtd

and tht main contacts optn btfort working on tht brtaktr.

Failurt to do so could rtsult in cutting or crushing injurits.

•

Do not ust a circuit brtaktr by itstlf as tht solt mtans of

isolating a high voltagt circuit. Rtmovt tht brtaktr to tht

Disconntct position and follow all lockout and tagging rults

of tht National Eltctrical Codt and any and all applicablt

codts, rtgulations and work rults.

•

Do not ltavt tht brtaktr in an inttrmtdiatt position in tht

ctll. Always havt tht brtaktr tithtr in tht Ttst or Conntcttd

position. Failurt to do so could rtsult in a flash ovtr and

possiblt dtath, ptrsonntl injury or proptrty damagt.
