Abbrivation	Expansion	description	More info
A	Amps / Ampere / Ampacity	Electrical Current is measured in Amps.	mA - is 1/1000th of a 1Amp
ACB	Air Circuit Breaker	It’s a electrical Switchwhich automatically protects the equipments in its path when there is a overload / Short Circuit	Used to control currents normally between 630A - 6000A
AL
APFC	Automatic Power Factor Correction	This equipment senses the Power factor in the system and automatically tries to bring it close to unity PF
AYFY	Aluminium Cable Specification	Aluminium Conductor, PVC Insulated, Galvanised Flat Steel Wire (Strip) Armoured and PVC Outer Sheathed Heavy Duty Cable.
BIS	BIS Bureau of Indian Standards
CAT	Category5 cable	Twisted pair cables for carrying data
CDG relay	Circular Disk gear Relay
CEIG	Chief Electrical Inspector to Govt
CT	Current Transformer	It’s a sensing equipment used for Ammeter which measures the current in a circuit
CU
DB	Distribution Board
DG	Diesel Generator	Its an equipment which gives power from the alternator driven by a diesel engine	Its capacity is measured in KVA
DP	Double pole	Ph with Neutral
EB	Electricity Board
EHT	Extra High Tension	Transmission Voltage 110 KV & Above	110 KV, 132 KV, 220 KV and 400 KV
EI	Electrical Inspector
FR	Fire Retardent	FR – The wires are insulated with special PVC compound material, which has high Oxygen & Temperature Index. This helps restricting the fire from spreading.
FRLS	Fire Retardent Low Smoke	Smoke FR – The wires are insulated with special PVC compound material, which has high Oxygen & Temperature Index. This compound emits low smoke while burning. This helps restricting the fire from spreading with low smoke, which enables better visibility.
FSU	Fuse Switch Unit	Its a switch with Fuse ( Fuse Unit Moves )	When the current exceeds limits in the circuit, fuse blows out and saves the equipment from damage.
