Do poor conductors produce more heat then the relatively good conductors?
Most of the metals are effective conductors of heat.They conduct heat without much loss in energy and quickly.Copper, silver are among best conductors of heat.metals are good conductor of heat.
Good conductors of electricity are often good conductors of heat?
Generally speaking, materials that are good conductors of heat are good conductors of electricity. But there is a notable exception. Diamond, an allotrope of carbon, conducts heat better than any metal, but it is an electrical insulator.
Are insulators dull brittle and poor conductors?
Insulators are conductors
What type of resistance do conductors have?
Conductors have a (low) Electrical resistance.
What are some good conductors and bad ones?
Good Electrical conductors: All metals, ionic substances (in solution or molten form) Bad Electrical conductors: Water Good Heat conductors: All Metals Bad Heat Conductors: Water
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
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 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.
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 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 phase conductor?
There is no such thing as a 'phase conductor'. The correct term is 'line conductor'. Line conductors are the three energised conductors that supply a three-phase load.
Is line to line fault a 3 phase fault?
'Line conductors' are the three 'hot' conductors (A-B-C) that connect a three-phase supply to a three-phase load. In some cases, a pair of line conductors (e.g. A-B, B-C, or C-A) is used to supply a single-phase load. A 'line fault' can be a short-circuit fault between all three, or any two, of these line conductors -whether they supply a three-phase load or a single-phase load.
Line to line voltage?
The conductors between a three-phase supply and a three-phase load are called line conductors not phase conductors, and the voltage measured between them are line voltages, not phase voltages. In the case of a delta supply, the line voltages are numerically equal to phase voltages, but the name remains the same!I have to admit that many people call line conductors 'phase conductors', but many people also say 'irregardless' -that doesn't make it a real word!!
What size service conductors for a 225 amp 3 phase service?
4/0 copper phases and neutral
What parts are necessary for a simple complete circuit?
-- power supply -- power-dissipating component -- connecting conductors
What is the wire that runs from the electric meter to the breaker box called?
Service Entrance Conductors.
