Best Answer

Conduit bodies are used to provide pulling access in a run of conduit, to conserve space where a full size bend radius would be impractical, to allow more bends to be made in a section of conduit or to split a conduit path into multiple directions.

What are all the materials used in making PVC conduit pipes?

Poly Vinyl Chloride is made from two main ingredients. These ingredients are chlorine and ethylene both of which are needed to make PVC conduit . UV inhibitors are also added to the ingredients to prevent degradation from exposure to the sun's rays.


What is the minimum size service cconduit for a 100 amp service?

If the service stack is supported by a support structure and the utility feed drop is not supported from the conduit, the size of the conduit can be 1 1/4". If the service stack is used to support the utility feed drop then the conduit has to be 2" schedule 40 conduit. The reasoning behind this is that if in a storm a tree limb falls across the service drop, the lighter weight conduit could bend and pinch the wires in the stack and short out. This would be ahead of the main service breaker and the only protection for the wire would be the primary fuse at the transformer. Theoretically this amperage could rise to 50000 amps before the primary fuse blows. A schedule 40 service stack if supported, as the code requires, will withstand most tree falls. What is most likely to happen is that the utility connectors will pull apart leaving the service stack intact.


How do you make floating ground in 100 amp sub panel Sub panel 30' from main panel and is grded to 2nd 10' rod wired to 1st 10' rod at the main panel. GFCI bkrs are nuisance tripping in bsmt location?

If the sub panel is in the same building remove the bonding screw that bonds the neutral bar to the panels enclosure. Remove the ground from the second ground rod. The sub panel is grounded by the ground wire from the sub panel's feeder. If the panel is separate from the main building treat the sub panel as a separate service. It will need its own ground rods and ground wire from the rods to the neutral bar of the sub panel. Leave the bonding screw in. There will be no ground wire in the conduit between the two services.


Where is the proper location for a main breaker in a panel?

Normally the main is on the top but you can install a service panel with the main on the bottom unless local codes prohibit it.

What are some examples of a tee joint in the electrical trade?

A tee joint in the electrical trade is a conduit fitting. It is used in conduit work where there needs to be a device connected into the main conduit run. An example of this is where a light switch needs to be installed into the conduit run. The main conduit run starts at the distribution panel and proceeds to a lighting fixture. On the way a switch is needed to operate the light fixture. In the main conduit run a tee fitting is installed so as to pick up the switch for the fixture. When the conduit system is complete the wire is then drawn in. The "hot" conductor is pulled to the tee fitting and then diverts to the switch box to pick up the switch and then back up the same conduit to the tee fitting and then on to the lighting fixture. Splices are not usually made in tee fittings.

What is the main reason for connecting a ground wire to the end of a conduit being used to protect the wire?

The main reason for connecting a ground wire to the end of a conduit is to ensure that the conduit itself is properly grounded. This helps dissipate any stray currents or faults, reducing the risk of electrical hazards and providing a path for fault currents to travel safely to ground.
