- B . 3
- C . 4
- D . 5
Which of the following is true when describing slip sleeves or gutters?

- B . 160
- C . 177
- D . 189
- E . 195
You are designing a horizontal pathway system where you will provide 100 mm (4 in) conduit and pull boxes. The building architectural elements will only allow for a single layer of conduits (not stacked). The main horizontal pathway system consists of five 100 mm (4 in) conduits. Large single sheath copper cables are not expected to be placed.
