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.

Can triplex be run in underground conduit?
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.
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.
What wire size is needed for 1800 amp service?
There is no one wire that is rated for 1800 amps. The service will have to be a quad parallel of the conductors. A 600 MCM conductor with an insulation factor of 90 degrees C is rated at 475 amps. This conductor paralleled into four equal lengths will give an ampacity of 1900 amps for each leg of the service.
What size conductors are needed to run a 400 foot residential underground electric service?
Need to know what size service is going to be installed at the end of the run.
What size ground wire for a 400 amp panel in Quebec?
This answer is taken from the CEC. Table 17 states minimum size of grounding conductors. For a service conductor drawing 400 amps a #3 copper grounding conductor is needed. Also see rules 10-206, 10-700 and 10-812 if you have access to the code book.
What size service ground is needed for a 350 parallel service?
The required size of the service grounding conductor for a 350 amp parallel service will depend on the specific installation requirements and local codes. It is recommended to consult with a licensed electrician or engineer to determine the proper size based on factors such as the type of wiring used, the distance between the service entrance and the transformer, and the local ground conditions.
How do you size the neutral in a 240 volt system?
On a 120/240 volt distribution the neutral is sized along with the supply conductors. The sizing is based on the amperage of the service distribution.
What size service conductors for a 225 amp 3 phase service?
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.
800 amp service using parallel sets of 500 cu what size grounding electrode conductor?
For an 800 amp service with parallel sets of 500 kcmil copper conductors, the grounding electrode conductor size should be based on the largest conductor in the parallel set. The grounding electrode conductor size should be sized based on Table 250.66 in the NEC, which recommends a minimum size of 3/0 AWG copper for 1/0 AWG or larger service-entrance conductors.
What are all of the conductors between the service equipment and the final branch circuit?
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.
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.
What size conductors are needed for 800 amp 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.
What does SN stand for in an old style fuse panel it is referring to the neutral bars?
The term SN refers to a panel or disconnect switch that has solid neutral bar installed. It is a small bar that allows the service conductors to be bonded to the enclosure at that point.

What size service conductors do you need for a single phase 600 amp commercial panel?
For a single phase 600 amp service, you would typically use 350 kcmil conductors. However, the specific size can depend on factors like voltage drop calculations, distance from the utility transformer, and ambient temperature. It's always recommended to consult with a qualified electrician or electrical engineer for a precise determination.

For a 100 amp underground service to an unattached garage what size hot and neutral copper conductors do you need?
For a 100 amp underground service to an unattached garage, you would typically need to use 3 AWG copper conductors for the hot wires and 3 AWG copper conductors for the neutral wire. This size will ensure that the conductors can safely carry the required current without overheating. Additionally, you may need to refer to local electrical codes and regulations for specific requirements in your area.
