Feeder Often refers set conductors that originates main
distribution center and supplies power one more
secondary branch distribution centers. EEPROMs retain
their contents when power turned off. Guidelines for various types of
electrical enclosures are provided the National Electrical
Manufacturers Association (NEMA).
Erasable Programmable type semiconductor memory often used for storage data
Read Only Memory (EPROM) programs that change infrequently, all. Explosion
proof enclosures are also available for other types equipment. Other types of
encoders provide digital signal representative absolute

Encoder Often refers digital device that provides angular position
information.
