Electrical Code Is To Promote Public Safety In Murrieta!

Keeping Up with Code: Why It Matters

An electrical code is a set of regulations for electrical wiring. The purpose of the electrical code is to promote public safety in a practical manner from hazards arising from the use of electricity. Keeping up-to-date with electrical codes can be overwhelming.

Failure of a home to be up to the current electrical code is often to blame. Electrical codes is an essential tool of the trade and describe the standards for safe electrical installations in detail. Interpretations of the electrical code can vary greatly among jurisdictions.

The intention of an electrical code is to provide standards to ensure electrical wiring systems that are safe and unlikely to produce either electric shock or fires.

Electrical Codes and Standards

National Electrical Code®

The National Electrical Code (NEC), sponsored by the National Fire Protection Association, protects the public by establishing requirements for electrical wiring and equipment in virtually all buildings. The NEC is the electrical industry’s most important document and the most widely adopted Code in the world. The entire Code is reviewed and revised based on new technology and industry needs every three years.

Electrical contractors and workers use the NEC for estimating, designing and installing electrical systems. Excellence in electrical contracting, services and safe installations are the results of staying current with the NEC requirements.

Codes and standards are adopted by local jurisdictions in the interest of providing safety regulations for consumers. Maintaining compliance with the requirements of the National Electrical Code®, together with provisions for proper inspection, represents the minimum necessary in the interests of the public and the industry.

An electrical code is meant to set standards for electrical wiring systems, to enhance safety and to protect against fires or electric shocks.

The National Electrical Code (NEC) and HVAC: The Basics

The National Electrical Code and Heating, Ventilation, and Air Conditioning have some shared roles for both electricians and HVAC Installers and technicians. There are some specific categories in the NEC that are applied to HVACand making calculations for circuits and wire sizing for HVAC appliances. Aside from the specific categories and chapters in the NEC are directly applicable to HVAC and HVAC appliances it is important that every technician have a basic understanding of the NEC in all aspects especially the categories and chapters that are specifically applicable to HVAC and HVAC appliances.

Admittedly the NEC can cause sleep and/or great frustration at times. Do not operate heavy machinery and make sure you take a deep breath if you become frustrated from reading the National Electrical Code. Seriously, the NEC is a serious book and important to understand especially for those responsible for sizing wire, disconnect boxes, and other related electrical devices for HVAC. In the commercial world in new construction an engineer would determine the correct wire sizes and disconnect boxes necessary for all the equipment.

Sometimes but not always in a the commercial retrofit market an engineer will also determine the correct size of all electrical devices necessary to replace or add HVAC equipment. Whether an engineer of record made the determination for sizing circuits and electrical devices it is always a good thing for the technician to know the correct sizes as the engineer of record determined.

The electrical code is intended to assure that electrical wiring in a building is functional, adequate, and most of all, safe, not only should electrical work comply with the code to be legal, it should comply with the code to be safe.

Cracking the Residential Electrical Code

It should be noted that pretty much all electrical work in your home, besides changing a lightbulb or a smoke detector battery, should be done by a licensed electrician. But that doesn’t mean you shouldn’t know what to expect in advance. After all, the best way to avoid being taken advantage of by a contractor is by simply knowing what’s involved in their work. Since this topic can be, and has been, covered in books as thick as an oak tree, today I’ll just be talking about the ins and outs of residential electrical code.

Keeping Current
The first thing to know about electrical code is that there is a mountain of information to absorb and it changes every three years, so no one has all of the information stored in their head (not even veteran master electricians). That’s why there are so many great resources available to help both homeowners and electricians keep track of the requirements.

GFCI Protection
A GFCI outlet (ground fault circuit interrupter) basically detects a difference in current between the line and load wires (which are usually supposed to be the same), so that the outlet or circuit will shut off before any real harm is done to a person or building. The practical application of this device is that it protects people from being fatally electrocuted if the outlet comes into contact with water. That’s why they are required in bathrooms, kitchens, basements, garages, exterior circuits, and anywhere else you might find water. Read full article here.

An Electrical Code Is For Practical Electrical Safety

Also keep in mind that you don’t want to (and by electrical code can’t) bury an electrical junction box so that it can’t be seen. The electrical codes can offer some direction when dealing with electrical conduit installed in roof systems or below roof decks. Often, rewiring residential electrical wiring to meet modern electrical code can seem like a daunting task.

As saving energy dollars becomes more important in plants, the electrical codes will now give guidance on the installation of smart grid management systems. I know the electrical code will be different from area to area, but if you’re looking for some general advice call us here: (951) 805-1262. Electrical Code will significantly boost worker safety, and save lives, say electrical contractors.
