What else can I help you with?
Is it permitted to use flexible conduit over 6 feet in length as a grounding means?
No. The new electrical code change does not allow any flexible conduit to be used as a ground means. It is now required to have a green ground wire pulled into the conduit with the other conductors in the flexible conduit. This grounded bonding conductor is not counted as wire fill when calculating the size of the flexible conduit to use
Is an equipment ground required in PVC conduit?
No, an equipment grounding conductor is not required in PVC conduit because PVC is non-conductive and does not provide a path for electrical fault currents to flow. However, it may still be required by code depending on the specific application and local regulations. It's always best to consult with a qualified electrician or local building code official for guidance.
Does breaker trip when circuit it is protectiong got wet?
Not unless the leakage current gets higher that what the trip setting of the breaker is. In many underground conduit systems the feeder conductors are in water continuously due to leaks in the under ground conduit system.
What is the main reason for connecting a ground wire to the end of a conduit being used to protect the wire?
== == Think about it. The conduit is metal, and can be touched by people. It is carrying live wires and is connected to steel junction boxes. What would happen if a hot wire accidentally touched the steel conduit? The ground wire is there to keep the conduit from going live in a fault condition. You want to ground any metal surface a user can touch in case of faults.
Can electrical wiring be on ground in crawlspace?
No, electrical wiring should not be placed on the ground in a crawlspace. It should be properly installed and secured to walls or studs to prevent damage and reduce safety hazards. Wiring on the ground can be exposed to moisture, debris, and pests, which can lead to potential electrical issues.
Does the metal conduit count as a ground?
No, each conduit must contain a separate grounding conductor.
Is equipment ground required in EMT conduit?
Yes it should be grounded

What does a frame-ground circuit use as a return wire?
a separate high capacity wire
Does breaker trip when circuit it is protectiong got wet?
Not unless the leakage current gets higher that what the trip setting of the breaker is. In many underground conduit systems the feeder conductors are in water continuously due to leaks in the under ground conduit system.
What information does a blue print provide to an electrician when they plan to run wires?
The print provides wire sizes, circuit layout, circuit loading, conduit sizes, conduit wire fill, under ground conduit positions and depth, breaker positions in distribution, electrical engineering company who designed the print, if there have been revisions made to the print, overload settings, fixture counts, receptacle counts and switch counts to name a few.
Are ground wires required in steel or aluminum flex conduits?
Yes, any flexible conduit that has live wires drawn into it must have a ground wire also installed with the "hot" conductors. The reasoning behind this rule is that the flex in the conduit is coiled and has a long length to it. The continuation of the grounding medium through the tightness of the conduit connectors to the flex was not considered a properly secured grounding system so to overcome this weakness in the grounding system, a ground wire now has to be installed.
What color is a ground wire in an electrical distribution?
The main electrical ground wire is sized to the service and is non insulted bare copper. Branch circuit grounds are green in conduit installations and bare copper again in house wiring cables.
To rewire a 2 bedroom property that was built in 1956 Can we use the old conduit or Do we need to replace it Currently earth is attached to the conduit itself Any special cables we can use?
If the existing conduit has not been intentionally or accidentally interrupted it is still an adequate ground. If you are in doubt about this or if a test proves that it is not grounded, new conductors including a new ground wire can be pulled inside the conduit. If the existing conduit is flexible conduit and it has "jake" type twist connectors, rewiring with a ground is advisable as those type of connectors do not maintain a good ground connection.
Is it necessary to ground at all metal junction boxes when using metal conduit or cable?
In a completely metallic conduit system it is not necessary to ground each junction box as long as the metallic system has the grounding capacity rating larger than that of the over current device protecting the circuit. The code book states what size conduits are rated at, for grounding amperages.
What is the two types of ground circuit?
1. direct ground circuit 2. virtually ground circuit
