Job Planning and Design
Planning decides what the C-7 license may install, where the telecommunications room goes, how every cable will route, and which code and coordination problems must be solved before rough-in. CSLB weights this section at 18%. For worked examples, named traps and a full practice exam at CSLB's weights, see the PrepPass C-7 Low Voltage Systems study guide.
Material Selection and Estimation
Choose cable, connectors, pathway and tools by category, rating and environment, then turn counts into footage, boxes, labor and a written proposal. CSLB weights this section at 15%. For worked examples, named traps and a full practice exam at CSLB's weights, see the PrepPass C-7 Low Voltage Systems study guide.
Wire/Cable Installation and Termination
Install and support pathways, pull without damage, terminate with the right tools and keep every cable labeled. CSLB weights this section at 12%. For worked examples, named traps and a full practice exam at CSLB's weights, see the PrepPass C-7 Low Voltage Systems study guide.
