||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\
corrosion but NOT UG)
||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\
- More expensive than PVC of material & labor intensity
||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\

thinner wall pipe than RMC ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\
||\\||\\ - IMC would be used near typical damage spots
||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\

||\\||\\ - RMC used near moisture
||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\

- Gives you 90 degree turn to go into a building
||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\
- Gives you a pull point to go into a building
||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\
- Good for changing directions
||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\
Junction boxes - correct answer✔✔- Pull point ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\
- Wire connection protection
||\\||\\ ||\\||\\ ||\\||\\
- Change in direction
||\\||\\ ||\\||\\ ||\\||\\
- 360 degree rule (no more than 4 quarter bends b/w pull points)
||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\
Pull boxes - correct answer✔✔- Same exact purpose as junction boxes, just typically an
||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\
outside J-box ||\\||\\
Gutter - correct answer✔✔Wireway or trough (when it's a long Junction box)
||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\
In-line metering - correct answer✔✔When the meter and disconnect are essentially stacked
||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\
