The document is completely reorganized for improved ease of use and features an expanded Article 100 that consolidates all the code's defined terms in one place to help you quickly locate critical NEC content.

Changes in the NEC 2026 include new, expanded, and revised content and provisions for:

All electrical systems, including the use and approval of reconditioned equipment, level/flat standing surfaces within the required working space for electrical equipment, servicing and maintenance of equipment, and opened electrical equipment doors that impede access to or egress from required equipment workspace.

Residential electrical systems covering ground-fault circuit interrupters (GFCI) for specific appliances, optional installation of receptacle outlets serving island and peninsular countertops and work surfaces, emergency disconnects of one- and two-family dwellings, the use of 10-ampere branch circuits, and an annex providing guidelines on the use of electrically powered medical equipment in homes and residential board and care occupancies

Commercial/industrial electrical systems accounting for everything from GFCI for specific appliances and the use of "replacement panelboards" to arc-fault circuit interrupter (AFCI) protection of sleeping areas of public safety and first responder facilities, disconnecting means in sight of luminaires using double-ended lamps to include LED type, and other considerations

Alternative energy systems and energy management addressing the interconnection of distributed on-site power supplies with electric utility supplies, the delineation between storage battery systems and emergency storage systems, commissioning energy storage systems (ESS), photovoltaic electric systems, emergency management systems, load calculations for outlets supplying electric vehicle supply equipment, and solar photovoltaic and wind power electric systems on floating structures and in offshore locations

New articles and requirements for never-before covered systems and equipment such as Class 4 fault-managed circuits, hazardous locations within commercial and industrial cannabis production facilities, equipotential bonding in and around areas with splash pads, insulated bus pipe/tubular covered conductor systems, flexible bus systems, germicidal irradiation lighting equipment, and more

CAN I GET A FREE ESTIMATE OVER THE PHONE, YES -PHONE/VIDEO CHAT!

Yes, over the phone or Video.

WhatsApp - SMS. Supports sending and receiving media: text, photos, videos, documents and voice calls.

For you free estimate - you can call/or send me a video, live video chat, pictures or text showing me what your electrical needs are.
Given me as much information as you can about your projeck.
I need to see, from point (A) to point (B).
What you want installed? or what the problume is your having?
And where you want it installed, or fixed. detailed as possible.
keep video, text, pictures, short.
Video/under 4 minutes.
I need to see? - Height,Length and wall distance. (optional) - tape measure, ifyou can.

Once i have all your information I'll get back with a work estimate ASAP.

FREE estimate

My estimate/calculations, could be wrong, based on distance, length, that could dramatically changes the work order estimate.

The best way to get a more accurate quote is to book an appointment today and have a tech come to your project and location, service call fee applys..$75.99

NOTE: On our appointment date if after I inspecting the job and its nothing like what i thought it was going to be, you will be notified immediately about the change order. If the new quote is satisfactory, were continued the work order.

If the quote is unsatisfactory and you decline service, that's your right. A service call fee of $75.99 will be rendered at the end of our appointment.

You will know what all charges are before we commence work based on our work order quote. No pressure when you work with us.

NOTE: Sometimes quotes over the phone can't be accomplished, or obtained and a service call is needed at your location book an appointment

All quotes are valid for thirty (30) days from the date of the quotation. If acceptance is received after this period has lapsed, the job may be required to be re-quoted.

An estimate is a non-legally binding document. It is an approximation of costs for a project!

WHAT'S DIFFERENCES BETWEEN AN ESTIMATE AND A QUOTE?

What’s an Estimate?

An estimate is basically a ‘guesstimate’ or rough, educated guess based on what a job MAY cost.

Often it is supplied either before you know all the details of a particular piece of work (such as during an initial call from a prospective new customer) or during a site visit.

Estimates are your first thoughts on costs and can change drastically when you get further information, when unexpected complications crop up during the work or the scope of what you have been asked to do increases.

Key point: An estimate is an informal idea of price based on limited information. Consider it a starting point in terms of costs, which can go up (or down). Estimates CANNOT be used as a legal standpoint for price.

What’s a Quote?

A quote (or quotation) is an exact price for the job being offered. As such it is fixed and CANNOT be changed once it has been accepted by the customer (unless the customer changes the amount/type of work required or you discover something completely outside of the scope of what was agreed).

Quotes are only issued after an onsite visit or where you are confident that you have established exactly what is needed.

Key point: It’s important to remember that quotes are presented formally and represent a contract between you and the customer. As such they can be used as legal standpoints for price should a dispute arise.

Understandably, quotes give customers peace of mind; safe in the knowledge that they know exactly how much the work will cost before the job begins.

SOME COMPANIES OFFER FREE SERVICE CALLS - WHY?

The only way a company can offer free service calls is to make it up on the Invoice, by Mark it up on the invoice and charging the consumer a higher rateby on the Invoice. So you're really not getting a free for a service call

At Dunbar's Electric we believe in offering quality service at a fair price and the only way we can do that is to charged a service calls fee to balance out the daily cost of operating a service business.

thank you for your time and understanding.

SERVICE CALL 101

A service call is simply a service that is rendered when a homeowner or business owner has a problem or malfunction that they need examined or diagnosed.

For example: let’s say that an owner of a house/ office is having a problem with his electrical. they smell burning,Breakers keep tripping, switch is not working, electrical plug start a fire. something's wrong, light installed, ceiling fan installation and or it’s creating discomfort, This individual would probably call a electrician service company to have them come out to diagnose the problem with the electrical system.

This would be considered a service call. This is would apply to any service that is needed. Whether it’s heating, air conditioning , electrical, plumbing, refrigeration ...etc. A service is needed. A service company is called to come out and provide that service. Fairly simply right?
