equipment
• Where electrical components are
being changed, they shall be fi t
for the purpose and to the correct
specifi cation.

2-8. Checks to electrical devices
• Repair and maintenance to electrical
components shall include initial
safety checks and component
inspection procedures.
• Initial safety checks shall include but
not limit to:-
-That capacitors are discharged:
