Although this method of identifying a grounded circuit conductor (may be a neutral) is acceptable for sizes larger than 6 AWG conductors in a raceway, it is not acceptable for multiwire cables.

For sizes larger than 6 AWG installed in a raceway, this is what Item 3 of 200.6(B) allows: "At the time of installation, by a distinctive white or gray marking at its terminations. This marking shall encircle the conductor or insulation."

This requirement appears in part (E) of 200.6: "Grounded Conductors of Multiwire Cables. The insulated grounded conductors of a multiconductor cable shall be identified by a continuous white or gray outer finish or by three continuous white stripes on other than green insulation along its entire length.

Multiconductor flat cable 4 AWG or larger shall be permitted to employ an external ridge on the grounded conductor.

What wire is neutral in an appliance chord?

It greatly depends on what you are considering an 'appliance'. For a typically small appliance in North America (Canada & USA) will use 'polarized' plugs. In the absence of a ground contact, one of the two blades will be slightly larger thus only allowing the plug to be inserted in one way. The smaller of the blades is for the Non-grounded, current carrying conductor (I.E. Hot, Black Wire, etc...) The larger blade is the for the Grounded, current carrying conductor (I.E. Common, Neutral, White Wire, etc...) The third contact (if present) is the Ground, or the 'Grounded, non-current carrying conductor. And when replacing a grounded plug, never substitute a grounded three prong plug with a non-grounded two prong plug (Also, do not remove the ground 'prong' to facilitate plugging into a non-grounded receptacle or cord, or use a 'Cheater') as the devices safety will be severely compromised and create serious fire & safety issues. Most larger appliances such as dryers and stoves use both L1 and L2, and may not have a true neutral. While you may see a 'White' wire on one of the contacts of the receptacle, it is typically being used as a Non-grounded, current carrying conductor and is actually a 'Hot' wire. It is best consult a licensed/certified electrician as improper connections can lead to both fire & safety hazards... On lamp cords where both blades are of equal size the neutral side of the wire has a raised rib along its length.


What is the maximum size of conductor that will fit on a 15 amp breaker?

By code, you would want to use a 14 awg conductor. Although you may be able to fit a larger conductor (12 or 10 awg) it would be useless to do.


Is a grounding 120 volt receptacle larger than an ordinary receptacle?

No, it just has an additional conductor to separate the neutral from the ground, and has a third prong in the receptacle to receive the appliance grounding conductor through the cordset.


Why are thick wires used to carry large current?

Wires are measurements of their cross-sectional area and are expressed in gauge. In general, the smaller the conductor, the smaller the amount of current that can flow thru it. Conversely, the larger the conductor, the m ore current that can be carries by it.

What affects a wires electron flow?

The size of the conductor is in direct relation ship to its rating capacity of carrying a current. The larger the diameter of the conductor the larger the amperage rating capacity of the conductor.


The larger the conductor the Higher the resistanc Lower the ampacity Higher the voltage Lower the resistance?

No. The larger the conductor the lower the resistance and the higher the ampacity.

What gauge conductor has the least resistance?

Resistance becomes lower as the cross sectional are of the conductor becomes larger. Hence higer the diameter of the conductor lower the resistance.


Why ascr dog conductor is called as a dog conductor?

"Dog" is the code name for a specific type of conductor ACSR conductor - 14.2mm in diameter with 7 small (1.57mm) strands of steel and 6 large strands (4.27mm) of aluminium, and can carry up to 455A of power. ACSR conductors are named after animals, with the larger/smaller the animal, the large/smaller the conductor is - a Dog conductor is larger than a Mole conductor, but smaller than a Zebra conductor.

IS a piece of sawdust larger than a cell?

A piece of sawdust is larger. The reason for this is because majority of cells are microscopic, compared to sawdust, which can be identified by the naked eye.
