What is a 1900 Electrical Box?A 1900 Electrical Box is defined as a standard 4 inches (4’’) square electrical switch box which is the combination of a gas and electrical box. It is the most commonly used box when a simple switch box is not big enough. 1900 Electrical Box 1900 Combination Gas and Electrical Box Cover There are usually two types of 1900 Electrical Box are available. 1900 Electrical Box 1900 Deep Electrical BoxTwelve 10 AWG (American Wire Gauge) can be installed in a 4-

What is CSST Bonding?CSST (Corrugated Stainless-Steel Tubing) bonding is a technique in which a conductor is electrically connected to CSST metallic gas piping and then connected to the grounding electrode system to provide a low impedance path to the ground. CSST Bonding is used to reduce the possibility and severity of arcing between conductive systems when energized by a lightning strike on a CSST gas pipe or nearby.The CSST must be permanently bonded to the grounding electrode system of the

What is a Dead Short?A dead short is an electrical circuit that results in current flowing along an unintended path with no resistance or impedance. This results in an excessive current flowing through the circuit, which can damage equipment or cause electrical shocks to those nearby.A dead short is difficult to track and diagnose as the current builds rapidly and trips the breaker immediately.It is mainly caused due to direct connection between positive and negative power wires or a direct con

What is Clamping Voltage?Clamping voltage is defined as the maximum voltage allowed to pass through an electrical circuit breaker or surge protector before limiting further voltage from passing through the circuit. The clamping voltage technique is used in modern electrical equipment to protect from electrical surges.The clamping voltage is a predefined voltage for a surge protector. The surge protector will restrict the input voltage from passing this number. Note that a surge protector is a de

What is Available Fault Current?Available fault current (AFC) is defined as the largest amount of current available during a fault. It is the maximum amount of current that can be delivered to the electrical equipment under a fault condition. The available fault current is also known as the available short-circuit current.The term ‘Available Fault Current’ was introduced in the 2011 NFPA 70: National Electric Code (NEC) in section 110.24 (latest version of the code).According to this section, i
