13 Topic: Pedestals (10m)
Instructions:
- Cover the following content as a group (either reading out loud or independently) then give an opportunity to answer any questions.
- Have students do the review questions independently, then take up answers.
In urban settings a pedestal acts as a junction box. No transformation occurs in a pedestal; the voltage that comes in is the same as the voltage that goes out. There is a main feed into the pedestal and multiple feeds out.
Pedestals must be set to the proper depth, square and level. They should be tamped in to prevent movement.
When the cable is installed, it should:
- Be tagged to show the house address it serves
- Be positioned so the cookies ( covered termination blocks ) will not “flop out” when the doors are opened.
Each pedestal has its own ground rod to provide protection.
