The conductors between the service equipment and the final branch circuit include service conductors, feeder conductors, and branch circuit conductors. Service conductors connect the utility service to the service equipment. Feeder conductors distribute power from the service equipment to the panelboard or distribution board. Branch circuit conductors then carry power from the panelboard to individual outlets, fixtures, and appliances.
YesIn Canada the answer is no. Triplex is an aerial rated set of conductors that are used to bring the voltage from the utilities pole to the service drop at the home. Triplex consists of two ungrounded conductors wrapped around a neutral steel supported conductor. These conductors can be used on higher current capacities due to the direct cooling of the conductors by the surrounding air. This is why you will see a service drop of number 6 conductors supplying a 100 amp service. For a three phase four wire system quadplex is used to make three phase connections to commercial and industrial services.
Desired service is what the customer expects that they should receive. Adequate Service is just the minimum service that the customer expects to receive. Superior service goes over and beyond Desired or Adequate Service.
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.
Supply service conductors are the electrical conductors that provide power from the utility company's distribution system to a building or structure. They carry electricity at a higher voltage level to supply the building's internal electrical system. These conductors are usually installed overhead on poles or underground in conduits.
For a 225 amp 3-phase service, typically you would use 3 sets of 3/0 AWG copper conductors or 250 kcmil aluminum conductors for the service entrance conductors. Make sure to consult the National Electrical Code (NEC) and local regulations for specific requirements.
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.
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.
the difference between the two is the zone of tolerance
Typically copper conductors that provide a phase of electricity.
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
For an 800 amp service, typically 4/0 AWG conductors are needed for the hot conductors and 2/0 AWG for the neutral conductor in a 3-phase system. However, it is recommended to consult with a qualified electrician to determine the exact size based on the specific installation requirements and local electrical codes.
