Electrical conduit is a tube which is used for routing the electrical wiring in a building or structure.
EMT is an conduit.EGC is equipment grounding conductor
EMT is installed by set screw or compression type couplings and connectors.
there are three basic types of conduits used in now a days.
1.rigid metal conduit
2.intermediate metal conduit
3.electrical metallic tubing
By using electrical metallic tubing we can eliminate the equipment grounding circuit.

Given: 100kVA single phase transformer, Z=1.5% Primary: 480V 2 wire Secondary: 120/240V 3 wire Install the above transformer to serve a branch circuit panelboard. The panelboard will be located 10' from the transformer. The primary side raceway is PVC and the secondary raceway is EMT. All calculations will conform to applicable NEC regulations. The primary side, overcurrent protection device, will be chosen based on the next available standard size of the full load amps of the transformer. The secondary side,...
