What size wire do you need going from a 20KW 83A generator to the main 200A automatic transfer switch?
In conduit? direct burial? distance?
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 are the disadvantage of steel conduit?
main disadvantage of Steel conduit A. Anternal condensation result insulation damage B. not with stand especially mechanical accident C. complete protection against Fire hazard D. it can be used as circuit protective conduct The main advantage of voltage transformer A. To get neutral wire B. To produce sufficient illumination. C. To gain extra voltage
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.
