Allowing motors or conductors to stay dry, unless designed for wet locations

Prematurely replacing deteriorated wiring

Following too closely to the Electrical Code when installing electrical equipment

Replacing burned fuses with ones of a higher rating

Allowing the accumulation of dust on a motor since this buildup will prevent heat from escaping, thus keeping the motor warm in cold ambient conditions

Keeping electrical equipment dry unless designed for wet locations

Using the equipment designed for the application

Checking any aluminum connections frequently for tightness and presence of corrosion

need only make contact, they need not be tight

will create large amounts of heat if not tight

can cause an arc if too tight

may operate on overload for specified duration

the equipment may be left running if the fire is put out with a C type fire extinguisher

the equipment should be de-energized as quickly as possible

the equipment should be left running until a backup power supply is available

the equipment may be immediately restarted once the fire is extinguished
