The 2 common metals used for conductors in the electrical trade are: ___________ and ______________. Aluminium has become more prevalent for larger C.S.A. conductors as it is cheaper and lighter but more brittle than copper. Current/ Copper/ Aluminium Thermoplastic-sheathed cable (TPS) consists of an outer toughened sheath of polyvinyl chloride (PVC) (the thermoplastic element) covering one or more individual cables which are PVC insulated annealed copper conductors. It is a commonly used type of wiring for residential and light commercial construction in many countries. The flat version of the cable with two insulated conductors and an uninsulated earth conductor all within the outer sheath is referred to as twin and earth. In mainland Europe, a round equivalent is more common. Flat cables (or festoon cables) are made in PVC and Neoprene and are used as trailing cables for cranes, open filed conveyors and shelve service devices. Flat cables offer the advantages of extremely small bending radius’s, high flexibility and minimum wastage of space.

  • Don't Be Confused by Your Fuse
    Head Office Neptronic® 400 Lebeau Blvd. HVAC Controls Electric Actuators Actuated Valves Montreal, Quebec, Canada H4N 1R6 Tel.: (514) 333-1433 Humidifiers Electric Heaters Fax: (514) 333-3163 Toll Free: 1-800-361-2308 Don’t be confused by your fuse: MCA and MOP for your humidifier explained Before we start, we need first to understand what MCA and MOP are. The minimum circuit ampacity (MCA) and maximum overcurrent protection (MOP) ratings provide a guide for safely connecting field-wired equipment to the building mains. Understanding these ratings, and their relationship to each other, is critical to properly selecting wire and circuit breaker sizes. What is MCA? Minimum Circuit Ampacity (MCA) is a calculated value that specifies the minimum main power wire size. It is also used to determine the minimum wire size required for a field wired product. This specification is necessary in order to guarantee that the wiring will not overheat under expected operating conditions. The wire size takes into account the normal current draw, aging of components and anticipated faults. More specifically, the MCA is the highest steady-state electrical current that the unit should see when operating correctly. What is MOP? Maximum Over-Current Protection (MOP) is a calculated value that determines the maximum size of the over-current protection device (fuse or breaker). There are different MOP equations depending on your application. The maximum overcurrent protection (MOP) is the maximum circuit breaker size required to properly protect the equipment under anticipated fault conditions. The MOP takes into account startup surges and component aging. Supply wiring must be rated to carry the amps shown as MCA.

Surprisingly, these components of the original wiring system are usually not the culprits of electrical fires, nor are they the best indicators if electrical fire hazard conditions are present. Though old and often well used, if the original electrical system has not been abused, for example by over-rating fuses or circuit breakers, or by cutting the original conductors to add on new circuits, the original electrical system will likely be found today to be in excellent condition. Focusing on these elements of the electrical system can easily miss the real electrical fire hazards. Study after study show, the vast majority of electrical fires in homes are a result of “handyman tinkering”, that being unauthorized individuals having made changes or additions to the original electrical system; changes or additions that were not in compliance with the electrical code. Handyman tinkering was particularly prominent in the 1960s, ‘70s, ‘80s and the ‘90s during time of home renovation. Faulty circuit breakers also play a significant role in causing electrical fires. One test conducted in Broken ground due to water pipe repair with PEX British Columbia in the 1970s found that circuit breakers over 15 to 20 years old were faulty, resulting in electrical fires.

  • Arc Fault Circuit Interrupter Explained
    What is an Arc Fault Circuit Interrupter? Courtesy of Wikipedia, the free encyclopedia An Arc Fault Circuit Interrupter (AFCI ) is a circuit breaker designed to prevent fires by detecting a non-working (i.e., non-intended/non-useful) electrical arc and disconnect power before the arc starts a fire. An AFCI should, but does not always, distinguish between a working arc that may occur in the brushes of a vacuum cleaner, light switch, or other household devices and a non-working arc that can occur, for instance, in a lamp cord that has a broken conductor in the cord from overuse. Arc faults in a home are one of the leading causes for household fires.[1] AFCI’s resemble a GFCI/RCD (Ground- Fault Circuit Interrupt/Residual-Current Device) in that they both have a test button, although it is important to distinguish between the two. GFCIs are designed to protect against electrical shock, while AFCIs are primarily designed to protect against arcing and/or fire. Electrical Code Requirements Starting with the 1999 version of the National Electrical Code (NEC, also called NFPA 70) in the United States and the 2002 version of the Canadian Electrical Code in Canada (CSA Standard C22.1), the national codes require AFCIs in all circuits that feed receptacles in bedrooms of dwelling units. This requirement is typically accomplished by using a kind of circuit-breaker (defined by UL 1699) in the breaker panel that provides combined arc-fault and over current protection. Not all U.S.A. jurisdictions have adopted the AFCI requirements of the NEC as written.
