Lastly, this class presents every significant change made to Chapter 6 in the 2020 National Electrical Code® (NEC-2020). Instrumentation and Process Control. Lesson 6: nec chapter 6: special equipment of the nec full. This article covers the theory behind the safety procedures necessary for these installations so the patient, the nurses, the doctors, and all others in close proximity will not be subject to spurious electrical currents and other similar hazards during the course of treatment. We begin with the definitions and "General Requirements" of Chapter 1, which are vital to every code that follows.
Pricing & Return Policies. Building Trades Dictionary. The last two common wiring methods acceptable for health care facilities that I will cover here are Type AC cable with individual conductors wrapped with paper and MC cable with all the conductors wrapped with clear plastic.

Purpose of a fuse; Lead-wire, cartridge, power, plug, and glass-tube fuses; Thermal-magnetic and low-voltage power circuit breakers; Circuit breaker tripping.
In this section, we will focus on the electrical BOS components and their functions as part of the PV system. There is a reference to this method of two separate equipment grounding systems in NFPA 99 as requiring a redundant grounding for the patient grounding system. New Article 425, Fixed Resistance and Electrode Industrial Process Heating Equipment, presents new regulations that were required within the industry for this type of equipment. Explain what to do if a person is a victim of electric shock. It has been approved as a national United States standard by the American National Standards Institute (ANSI), and is formally identified as ANSI/NFPA 70.
