Even if you’re new to the electrician trade Cheap New Balance 574 Sale , you’ve likely heard of the NEC (National Electrical Code). Okay, so “NEC code update” is a bit redundant with the word “code” used twice. It seems only human nature to want to clarify things鈥攍ike “PIN number” so that we know we’re not talking about a slender metal rod with a sharp point. But that’s the point of the code updates鈥攖o clarify things and to make things in the industry even safer.
Over 5000 code change proposals were considered for the NEC in 2011 and nearly 3,000 public comments were judged during the review process. Also Cheap New Balance 574 Pink , three new articles were added.
Keeping Pace with Technology
This baby has been around since 1897, so it has seen lots of changes. Much of the electrical equipment we know so well today wasn’t even a dream back then. New technology breeds new safety concerns. Even the fact that today’s world is increasingly more electronic means that there is more demand for electricity. That means more wires crowded into a static space. New demands are being placed on this technological resource and the code needs to keep up.
Refinements in Safety Protocols
The NEC is an organic document. It lives and breathes with the experiences of the industry. When a former standard is found to be lacking in some fashion, recommendations are made to take into account factors which previously had been unknown or ignored as unimportant. The code grows and changes as new observations are made and considered.
Clarification in Wording and Organization
Occasionally Cheap New Balance 574 Green , what was formerly considered adequate wording in the code may be realized as potentially confusing or misleading. These problems are a matter of semantics and organization. Some of the changes may seem subtle or even insignificant, but the point of such changes is one of achieving greater clarity and greater ease in finding needed material.
To give you an example, consider NEC article 250. Here Cheap New Balance 574 Burgundy , the 2011 code attempts to spell out that bonding and grounding are directly connected ideas and not two different concepts.
Also, article100 includes many changes to the definitions of terms. This is important so that everyone who reads the code will all be on the same page when it comes to the meanings of the electricians’ vocabulary.
Perhaps the simplest single addition defines “ground” merely as “the earth.” That any electrician would not know this is incredible. Of course, the only way to ground an electrical system is into the earth. This merely sets the record straight so that any newbie won’t start getting strange ideas that could get him or others hurt or killed.
