  • 2020 National Electrical Code® Style Manual
    2020 NATIONAL ELECTRICAL CODE® STYLE MANUAL 1 FOREWORD August 2020 The National Electrical Code® is used nationally and internationally as the basis for safeguarding persons, buildings, and their contents from hazards arising from the use of electricity. It is vitally important that the text be as explicit as possible, and that maximum consistency be achieved in the language used in the text. The Code contains those provisions considered necessary for safety and thus is widely used as a basis for legal enforcement in the installation of electrical conductors and equipment in buildings and certain other premises (as detailed in the Code itself); this places a major responsibility on those involved in the preparation of document text to use forms of expression that promote uniform interpretation. The National Electrical Code Correlating Committee has recognized these responsibilities and has issued this manual. Preparation and Date of Adoption. This manual was originally prepared by the Editorial Task Group of the National Electrical Code Committee and adopted by the National Electrical Code Correlating Committee on May 13, 1969. It was amended September 22, 1975, October 11, 1984, October 12, 1989, and May 9, 1994. In January 1999, the Correlating Committee Task Group on the Usability of the NEC rewrote the manual. It was adopted by the National Electrical Code Correlating Committee on March 19, 1999 and by the Standards Council on April 15, 1999. It was amended March 1, 2001, January 15, 2003, and August 9, 2011, August 2015, and December 2020. 2 TABLE OF CONTENTS Foreword ........................................................................................................ 2 Chapter 1 General 4 1.1 Purpose ............................................................................................

  • Electrical Inspection Checklist for One-Family Homes Based on the 2020 National Electrical Code® (NEC®)
    Electrical Inspection Checklist for One-Family Homes Based on the 2020 National Electrical Code® (NEC®) NOTE: The Board of Electricity adopted the 2020 National Electrical Code (NEC) with an effective date of Nov. 17, 2020. Accordingly, the Department of Labor and Industry began enforcing the 2020 NEC on Nov.17, 2020. Electrical work authorized by permits issued on or after this date must comply with the 2020 NEC. Electrical license examinations are based on the requirements of the 2020 NEC beginning Jan. 1, 2021. However, due to concerns regarding the availability of 2-pole GFCI circuit breakers, the department delayed enforcement of the requirements for 250-volt GFCI receptacles and outlet requirements found in NEC 210.8(A) and 210.8(F). On April 5, 2021, DLI will begin enforcing the 250-volt GFCI receptacle and outlet requirements found in NEC 210.8(A) and 210.8(F). Industry circuit breaker manufacturers have confirmed that supply-chain challenges will be resolved in March 2021. Electrical work authorized by permits issued on or after April 5, 2021, must comply with the 2020 NEC. 001 An owner (i.e. homeowner) who files a Request for Electrical Inspection form (i.e. permit) with the Department of Labor and Industry or other electrical inspection authority is signing an affidavit and declaring they own and occupy the residence and they will personally perform all of the electrical work, including the planning and laying out of the electrical work. 002 The term “owner” is defined in law as a natural person who physically performs electrical work on premises the person owns and actually occupies as a residence or owns and will occupy as a residence upon completion of construction.

  • Don't Be Confused by Your Fuse
    Head Office Neptronic® 400 Lebeau Blvd. HVAC Controls Electric Actuators Actuated Valves Montreal, Quebec, Canada H4N 1R6 Tel.: (514) 333-1433 Humidifiers Electric Heaters Fax: (514) 333-3163 Toll Free: 1-800-361-2308 Don’t be confused by your fuse: MCA and MOP for your humidifier explained Before we start, we need first to understand what MCA and MOP are. The minimum circuit ampacity (MCA) and maximum overcurrent protection (MOP) ratings provide a guide for safely connecting field-wired equipment to the building mains. Understanding these ratings, and their relationship to each other, is critical to properly selecting wire and circuit breaker sizes. What is MCA? Minimum Circuit Ampacity (MCA) is a calculated value that specifies the minimum main power wire size. It is also used to determine the minimum wire size required for a field wired product. This specification is necessary in order to guarantee that the wiring will not overheat under expected operating conditions. The wire size takes into account the normal current draw, aging of components and anticipated faults. More specifically, the MCA is the highest steady-state electrical current that the unit should see when operating correctly. What is MOP? Maximum Over-Current Protection (MOP) is a calculated value that determines the maximum size of the over-current protection device (fuse or breaker). There are different MOP equations depending on your application. The maximum overcurrent protection (MOP) is the maximum circuit breaker size required to properly protect the equipment under anticipated fault conditions. The MOP takes into account startup surges and component aging. Supply wiring must be rated to carry the amps shown as MCA.

  • Wiring a Wall Section
    Youth Explore Trades Skills Electrician Wiring a Wall Section Description The activities that have led up to wiring a wall should have given students the skills and knowledge to culminate with this activity. This activity could be an opportunity to conduct a summative assessment of students’ previous knowledge of theory, safety, code, and wiring methods. Wiring a wall section will introduce students to a few new CEC rules and wiring methods. Having a wall section is obviously a requirement for this activity. The wall section could be full scale or smaller; to make this activity relate to the real world, it’s recommended that the wall section be at least 4' wide by 4' tall. The wall section shown in Figure 1 would be optimal, as it has some real (although scaled down to half size) features such as door and window openings, as well as a corner section, which will help students learn about routing wire and placement of device boxes in relation to these features. Figure 1—Sample wall section Building a wall section for a class requires a substantial amount of lumber and time. Optimally, this activity would work well with students having completed the carpentry portion of the course first. This activity is an opportunity for students to wire a wall to code specifications and with the teacher’s supervision, energize and test their circuits. Students will likely work in small groups, depending on the availability of material and the number of walls available. The students should have the opportunity to wire their wall sections individually, to give the teacher a clear picture of each student’s skills and competencies.
