Is it better to use metal or pvc conduit?

PVC conduit is better then metal as it won't corrod under ground and theres less of a chance of electrical shortages.


Which one is cheaper PVC conduit or emt conduit?

PVC is cheaper but is used differently. PVC is usually baried in ground and emt usually runs exposed. You can use PVC exposed if it is schedule 80 gray PVC electrical conduit. Schedule 40 is for under ground


Can you run Ethernet out doors or should it be incased in conduit?

The outer casing of an Ethernet cable does not have a UV rating and will deteriorate under the summer sun. Pull the cable into a conduit and if possible bury the conduit underground. This will give you a safe and secure link.


Does the white and ground wire connect to same ground bar in a meter base?

There should be no ground wire in the meter stack from the mast head to the meter base. If the meter base to distribution panel conduit is PVC, then a green grounding conductor must be pulled into the conduit. This green wire is independent and isolated from the neutral wire and should never be terminated together at this point. Only the line service conductors and the neutral wire go through the meter base. The neutral goes through a lay in lug. This type of lug requires the insulation to be stripped of of the wire where it passes over the lug. This stripped wire is then laid into the lug and is secured to the meter base by the removable top piece of the lug. The neutral wire remains unbroken from the mast head to the distribution panel's neutral buss bar. Using this lay in lug the watt meter picks up the neutral wire for the plug in meters operation. If your terminology is not correct and you mean the "distribution panel" instead of "meter base" then the answer is no. There are two individual buss bars in the distribution panel. In some panels there may not be an actual "ground buss bar" but ground screws lined up in a row in the back of the distribution panel's enclosure. In all distribution panels there is a neutral buss bar where all of the neutral conductors from the branch circuits connect. Do not mix the bare ground wires and the white neutral circuit wires under this neutral buss bar.


Does triplex wire need to be in conduit under a house?

Yes. If they are single wires they need to be in a conduit.


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 minimum depth in feet that a grounding rod must be driven into the ground?

Ground rods in the U.S. on a residential home are 8 foot long and are driven 8 feet into the ground. The top of both ground rods should be flush or just under the surface. One ground rod is placed directly under the meter base and another one is placed 6 feet to either side. They are connected together and grounded to the meter base with the correct size ground wire based on the amperage of the serviced being installed.

What size ground wire to water meter for 400 amp service?

You need 2 ground rods of 8' in length. One under the meter base and another one 6' to either side of the meter base. Drive them into the ground with just enough sticking up to connect the ground wire.

How do you megger test a 240 1ph under ground service?

If the service is connected you can not megger the service ahead of the main breaker. If the service is waiting for connection all you can do is megger between the wires. As the underground service is installed in PVC conduit, no ground circuit will be available between the underground conductors and the PVC conduit. Connect the black lead to the neutral bar in the meter base. Connect the other lead to the L1 lead and ring it. Do the same to the L2 lead. Then disconnect the lead from the neutral bar in the meter base and connect it to L1. Connect the other lead to L2 if it is not still connected from the last operation. Ring the line between L1 and L2. If you get a reading of infinity on all three tests then the service is good for connection.
