This Commercial Wiring Course is a 12 month access course based on the 2023 National Electrical Code. This new edition thoroughly and clearly explains the NEC ® changes that relate to typical commercial wiring.
The National Electrical Code is used as the basic standard for the layout and construction of electrical systems. To gain the greatest benefit from this text, the learner must use the National Electrical Code continuously.
This course takes the learner through the essential minimum requirements as provided in the National Electrical Code for commercial installations. In addition to Code minimums, the reader will find such information above and beyond the minimum requirements.
The commercial electrician is required to work in three common situations: where the work is planned in advance, where there is no advance planning, and where repairs and service are needed. The first situation exists when the work is designed by a consulting engineer or by the electrical contractor as part of a design/build project. In this case, the electrician must know the installation procedures, be able to read and follow the plans for the project, be able to understand and interpret specifications, and must know the applicable Code requirements. The second situation occurs either during or after construction when changes or remodeling are required. The third situation arises any time after a system is installed. Whenever a problem occurs with an installation, the electrician must understand the operation of all equipment included in the installation to solve the problem. And as previously stated, all electrical work must be done in accordance with the National Electrical Code and any local electrical codes.
Allow up to 5 business days to receive access codes. You DO NOT access this course from this website.
