How many ADDC cable from transformer to mdb?
The number of Aerial Bundled Conductors (ADDC) cables required from a transformer to a Main Distribution Board (MDB) depends on the load demand, the transformer capacity, and the specific design requirements of the electrical system. Generally, a single cable can suffice for lower loads, while larger loads may necessitate multiple cables to ensure adequate current-carrying capacity and minimize voltage drop. It's essential to consult local electrical codes and standards, as well as conduct a load analysis, to determine the appropriate number and size of cables for the installation.
Which cable is best for transformer incomer?
The best cable for a transformer incomer typically depends on factors such as the voltage rating, load requirements, and installation conditions. For medium voltage applications, XLPE (cross-linked polyethylene) insulated cables are commonly recommended due to their excellent thermal and electrical properties, as well as resistance to environmental factors. For low voltage applications, PVC (polyvinyl chloride) insulated cables might be suitable. It's essential to consult local electrical codes and standards to ensure compliance with safety and performance requirements.
What is cable glanding?
A device designed to permit the entry of a cable into an electrical equipment and which provides sealing and retension. Cable well tightened with supporting of cable holding material into an electrical equipment or panels.
What does the terminology - radial feed - mean in relationship to transformers?
This terminology usually refers to pad mounted transformers. A "radial feed " transformer is a transformer that has one bushing for the high voltage cable line. The high voltage cable terminates into the transformer through the transformer's bushing. There is no second bushing for the high voltage cable to continue further down the line. This type of transformer is usually on the end of a loop feed circuit. This is different from a "loop feed" transformer whose incoming cables are terminated at the primary bushings. On this type of transformer there is a second bushing which connects to the outgoing primary voltage cables that allows the primary to feed another transformer. Each pad mount transformer's secondary feed usually supplies enough power to connect up to four homes.
What is the difference between armored cable and flexible metallic conduit?
Armored electrical cable contains insulated electrical service wires protected by a flexible steel covering. Metallic Conduit is a tube or pipe though which we lay electrical cable.(Most commonly lighting cables).
Which standard covers the cable sequence in cable trench?
The CEC and NEC both cover this in the electrical code of the particular country.
What type of cable connector is recommended for a garbage disposal unit?
A garbage disposal unit typically requires a standard electrical cable connector for installation.
What are the advantages of using a 3 wire electrical cable for residential wiring?

What is a main distributors service cable and what is it connected to when first enering a build?
The main supply will first come from the power company to a transformer to reduce the voltage then from the transformer to the weatherhead then through the house meter to the main disconnect on the outside of building then to the switchgears main. The cable coming from the transformer to the meter and to the top of the main disconnect is the Main service cable
