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

What is Electric Heating?Heating is required for both industrial and domestic purposes. In industries, heating is required for the melting of metals, moulding of glass, enamelling of copper, baking of insulator and welding etc. In domestic purposes the heating is required for cooking, water heating, room heating in winter, pressing clothes and many more.All those purposes of heating can be fulfilled by electricity. Electric heating has some advantages. Electric heating is free from dirt hence mi

An electric water heater is a device that uses electricity to heat water for domestic or commercial purposes. Electric water heaters can be classified into three main types based on their design and function: normal plate heaters, immersion heaters, and geyser heaters. Each type has its own advantages and disadvantages, as well as safety precautions to follow. In this article, we will explain how electric water heaters work and their types in detail.What is a Normal Plate Heater?A normal plate h

This is one of the simple forms of electric wiring systems. This is little bit old/conventional wiring system. Now days we very often use this cashing capping electric wiring system. As the name referred in this wiring, PVC insulated wires are placed in plastic cashing and covered with cap. The cashing is of rectangular cross section as shown.The color of cashing channel and cap are normally white or grey. The cashing channel and cap are normally made of either plastic or wood. The channels and

What is Electrical Wiring?Electrical wiring is the electrical power distribution through the wires in a perfect manner for economic use of wiring conductors inside a room or building with better load control.Electrical wiring system is classified into five categories: Cleat wiring Casing wiring Batten wiring Conduit wiring Concealed wiringCleat WiringMaterial Used in Cleat Wiring VIR or PVC insulated wires Weather proof cables Porcelain cleats or plastic cleats (two or three grooves) ScrewsProce

We have already discussed the Fourier series in exponential form. In this article we will discuss another form of Fourier series i.e. Trigonometric Fourier series.Fourier series representation in Trigonometric formFourier series in trigonometric form can be easily derived from its exponential form. The complex exponential Fourier series representation of a periodic signal x(t) with fundamental period To is given bySince sine and cosine can be expressed in exponential form. Thus by manipulating t
