Heavy Duty Distribution Boards

Whether electricity is produced from natural gas, coal, oil, nuclear, hydroelectric systems, wind or solar, it goes through three basic production stages – generation, transmission and distribution. Each stage does pretty much what it says on the tin. Electricity is generated through the conversion of thermal energy to electrical energy, transmitted to regional and local substations, and distributed for industrial, commercial and residential use.

We’re all familiar with domestic distribution boards – every home has one. They house the circuit breakers and ground leakage protection units, which take in power from a transformer or upstream panel and distribute it to various individual circuits or consumer points. They typically have a single incoming power source and include a main circuit breaker and a residual current or earth leakage protection device.

The core function of any distribution board is to allow individual circuits to draw power from correctly-rated circuit breakers and isolate those same circuits if needed, without disrupting the rest of the supply. Its most important function, however, is one of safety, and they are built with short circuit as well as overload protection systems. This offers essential protection to people and equipment against electric shock, or fire caused by ground faults.

Heavy Duty Distribution Boards

Unlike domestic distribution boards, which only have to distribute power to a comparatively small number of low voltage appliances, heavy-duty distribution boards are used whenever a lot of power has to be distributed to multiple smaller channels. They are often used for concerts and other big outdoor events, caravan parks, horticultural installations and marinas, as well as in big, power-hungry industries such as agriculture and mining.

Because of the often quite extreme nature of their applications, heavy-duty distribution boards are specially designed and constructed to protect their circuitry from environmental hazards, such as dust and water.


Floor Standing Units

Heavy-duty distribution boards can be wall mounted or free standing. Free (or floor) standing units are used for heavy-duty electrification requirements such as automatic transfer switch panels, capacitor banks and main distribution panels. Generally speaking, wall-mounted boards handle amperages below 400A, while floor standing units handle from 400A upwards.

JB Switchgear is an experienced manufacturer and supplier of floor standing, heavy-duty distribution boards with current ratings up to 6000 amps. All our boards meet the latest national and international safety and performance standards, so you can be assured of the highest safety and performance levels. Chat to us today about how we can help you with the selection, application and manufacturing of a heavy-duty distribution board to meet your needs.
