Installing Electrical Boxes
This is an essential course for techs, helpers and AHJs. Electrical rough-in is one of the most mistake-laden aspects of fire alarm installation. Code violations abound and can cause expensive headaches for years.
Understanding proper equipment and methods is crucial for anyone installing installing electrical boxes for fire alarm system use.
For inspectors, understanding proper electrical box installation is key to determining whether a fire alarm system complies with code requirements.
In this course, you will learn about a wide variety of electrical boxes and various methods for surface mounting and flush mounting in new and existing work. This includes ceilings, beams, steel columns, sheetrock walls, concrete walls and outdoor locations. You will learn how to build good junction boxes and riser cans and how to make fire alarm control unit installation and maintenance easier. You will also learn code requirements for box fill, labelling and mixing power limited fire alarm cabling with 110 VAC wiring.
After completing this course, you should understand:
- The different types of boxes that are used for fire alarm system installation
- How to choose the best box to use for different fire alarm devices
- Multiple methods to surface mount electrical boxes (and other things) to sheetrock, concrete and metal surfaces
- How to reduce water intrusion into weatherproof backboxes
- Multiple methods to improve the aesthetics of surface mounted boxes
- How to flush mount electrical boxes in new drywall
- Multiple methods to flush mount electrical boxes in existing drywall, including jobs where wire is required to be run in raceway
- Multiple methods to flush mount electrical boxes in ceilings
- Multiple methods for installing junction and pull boxes
- How to use gutters to make fire alarm control unit installation and maintenance easier
- How to add a knockout anywhere one is needed
- How to connect EMT and other connectors to knockouts that are larger than the fitting
- NFPA 70 requirements for box fill
- NFPA 70 requirements for labels
- NFPA 70 requirements for mixing power limited fire alarm wiring with 110 VAC and other nonpower limited wiring
- How to use a MR101C to separate fire alarm wiring from 110 VAC and reduce the likelihood of high voltage damaging fire alarm equipment
