The purpose of the NESC is to provide safety for the public from utility lines. It governs clearances and other items that could create hazards for the public or hamper public servants from performing their duties. Examples are clearances of electric lines from pools, or from earth to conductor heights or conductors in front or around windows. The distance poles are from fire hydrants is another example of an NESC violation and serves as an example of hampering someone from performing their duty. It should not be confused with the National Electrical Code (NEC) which is for house and premise wiring methods and is not followed by electric utilities.
I am trying to find out myself, having found odd harmonics coming thru the neutral wire with my breakers open...I've been trying to identify the source of a strange hum/vibration in my home. If you mean the NEC, they have no power over electrical utilities. Your in home neutral wire should be at ground potential so there should be 0 volts to ground.
The minimum clearance from water spray equipment to live uninsulated electrical components at 161 kV is typically governed by safety standards and regulations. According to industry guidelines, such as those from the National Electrical Safety Code (NESC) or IEEE standards, the minimum distance should generally be around 3 to 4 feet. However, it is essential to consult specific local codes and the equipment manufacturer's recommendations for precise requirements. Always prioritize safety and adhere to the most stringent guidelines applicable in your area.
According to SOWPODS (the combination of Scrabble dictionaries used around the world) there are 1 words with the pattern E--NESC-. That is, eight letter words with 1st letter E and 4th letter N and 5th letter E and 6th letter S and 7th letter C. In alphabetical order, they are: evanesce
The regulatory body guiding the structure under high tension transmission lines typically includes federal and state agencies, such as the Federal Energy Regulatory Commission (FERC) in the United States, which oversees interstate electricity transmission. Additionally, state public utility commissions (PUCs) regulate local utilities and ensure compliance with safety and operational standards. These agencies establish guidelines for the construction, maintenance, and operation of high tension lines to ensure safety, reliability, and environmental protection. Compliance with the National Electrical Safety Code (NESC) is also crucial in these regulations.
One modern "expert" has written that the place-name Nescopeck is "An Indian word meaning "black, deep, and still water." Ignoring the impossibly vague term "Indian word", there is no native American language that can express three different concepts (black, deep and still) in such a short word. Another writer claims that it is an Algonquian word for "black spring", which seems far more likely.Since the place is said to be in north-eastern Pennsylvania the language should be Unami (Lenape). In that language water is mpi and black is sëke or sLike-; clearly neither of these appear in the word nescopeck.One very archaic Lenape word for a lake is scheyjunuppek, which could comprise two elements (big + pool of water), with -uppek looking very close to -opek. If the nesc- element is similarly archaic and means dark or deep or something of that kind, the word would make sense as "black pool or spring".
for 415V phase to earth min clearance is 25mm pallavCommentYou cannot have a voltage between a 'phase' and earth. You should be asking the clearance between a 'line' and earth.
