What is a service lateral conductor?
service lateral conductors are the underground conductors between the utility electric supply system and the service point, basically the cables that bring power from the transformer to the power meter in an underground service
Can the load wires in an electrical service panel exit from the same end as the service cable and meet code?
Per the 2011 National Electric Code, Art 230 Services:230.7 states:"Conductors other than service conductors shall not be installed in the same raceway or service cable."Exception #1: Grounding conductors and bonding jumpers.Exception #2: Load management control conductors having overcurrent protection.
What size conductors are needed for 800 amp service?
500
What size service conductors for a 225 amp 3 phase service?
4/0 copper phases and neutral
What is the wire that runs from the electric meter to the breaker box called?
Service Entrance Conductors.
What is a feeder circuit?
Definition from the National Electrical Code Article 100:Feeder. All circuit conductors between the service equipment, the source of a separately derived system, or other power supply and the final branch-circuit overcurrent device.Branch Circuit. The circuit conductors between the final overcurrent device protecting the circuit and the outlet(s).
What is the cable between the service panel and electric meter called?
Whether you have an overhead or underground feed, that section of the installation is referred to as Service Entrance Conductors. On an overhead installation, it includes the conductors on BOTH sides of the meter, from the service drop conductors (attached at the service head) to the service equipment LINE terminals. On an underground installation, it refers only to the conductors between the meter's LOAD side and the service equipment LINE terminals. The conductors on the LINE side of the meter come from a distribution transformer and are unbroken between the transformer and your meter.
How hard is it to upgrade if you have a 100 Amp service and want to change to 200 Amp with a new breaker panel?
=== === == == The process of replacing the equipment that comprises your service is simple and straightforward.1. Get a permit.2. A trained person cuts the service conductors so that they don't interfere with the utility company lines [so they can splice back in]!3. Remove the circuit conductors from the old panel.4. Demolish the old service.5. Install the new service.6. Reconnect the circuit conductors.7. Tie the new service cable back into the utility lines.8. Call for inspection.As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.Before you do any work yourself,on electrical circuits, equipment or appliances,always use a test meter to ensure the circuit is, in fact, de-energized.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.

What is the definition of the connection between the grounded circuit and the equipment grounding conductor at the service?
2008 NEC - Article 100 Definitions - Bonding Jumper, Main Main Bonding Jumper is the answer.
What happens if a megger test fails?
If a megger test fails you have a short between the two wires or the wire to ground that you are testing. This short circuit has to be repaired before the equipment is placed back into service.
What are feeders in power system?
"Feeders" are conductors which carry electric power from the service equipment (or generator switchboard) to the overcurrent devices for groups of branch circuits or load centers supplying various loads.
Can the load wires in an electrical service panel exit from the same end as the service cable and meet code?
Per the 2011 National Electric Code, Art 230 Services:230.7 states:"Conductors other than service conductors shall not be installed in the same raceway or service cable."Exception #1: Grounding conductors and bonding jumpers.Exception #2: Load management control conductors having overcurrent protection.
What is electrical feeder?
Feeders are commonly used to supply power to or from a radio antenna. A feeder can be a pair of parallel wires with closely controlled spacing (twin-wire feeder), or a single wire inside a hollow cylindrical conductor (coaxial feeder. <<>> In Canada the electrical term "feeder" is usually used incorrectly as a substitution for the terms wire or conductor. It is correctly defined is, any portion of an electrical circuit between the service box or other source of supply and the branch circuit over current devices. In the U.S. of A, a feeder definition taken directly from the National Electrical Code: All circuit conductors between the service equipment, the source of a separately derived system, or other power supply source and the final branch-circuit overcurrent device.
What size conductors are needed for 800 amp service?
500
What is the minimum size neutral for three sets of parallel 500kcm copper conductors for a service?
On large service entrance services the neutral can be reduced. The amperage of the service and the voltage of the service and the insulation factor of the 500 MCM conductors need to be stated to answer this question correctly.
What is single phase 480?
The utility company can provide a 480 volt, single phase service from a single phase transformer, usually with a three wire service. 480 volts is measured between the two line conductors, and 240 volts is measured between either line conductor and the common neutral conductor. The voltage of the line conductors are at 180 degrees with respect to the neutral conductor.
