Ensuring the safety of staff and equipment in commercial and industrial settings is a major priority for any company. Low voltage switchboards are one such critical component that safeguards an electrical system and may even help to reduce overall maintenance costs. This article will cover the benefits a low voltage switchboard provides for your facilities.
What are Low Voltage Switchboards?
A low voltage switchboard is responsible for distributing power to various connected circuits within a commercial or industrial facility. By controlling the flow of electricity, they ensure power is evenly distributed based on the different electrical needs of lighting, machinery, and equipment throughout the facility. It also helps reduce the risk of electrical hazards, including overheating and short circuits. Should an electrical fault occur, the switchboard will immediately cut off power to the affected circuit to prevent serious complications.
A switchboard consists of multiple components, including the essential circuit breakers and fuses that serve to protect the entire electrical system. The circuit breakers will open and close specific electrical circuits to protect the whole system from electrical faults. Meanwhile, fuses will melt when overheating occurs due to excess current flow, thus breaking the circuit to safeguard your system.
As their name suggests, these switchboards handle operating voltages below 1,000 volts, though this may sometimes differ across models and use cases.
Types of Low Voltage Switchboards
There are several types of low voltage switchboards available, depending on specific commercial or industrial needs.
Main Distribution Boards (MDBs)
MDBs are considered the heart of an electrical system. They primarily serve to distribute power from a single source (which can be a generator or transformer) to multiple secondary circuits. Typically, an MDB may distribute power to sub distribution boards (SDBs) or other circuits. Unlike standard low voltage switchboards, MDBs are rated to manage higher current levels effectively and are mainly used in commercial and industrial settings.
Sub Distribution Boards (SDBs)
SDBs, or breaker panels, will distribute electrical power received from an MDB into smaller subsidiary circuits. It also serves as a safety measure with the inclusion of a circuit breaker or fuse for each connected circuit.
Motor Control Centres (MCCs)
MCCs serve to manage and protect electric motors within a facility. They typically feature modular compartments that allow for easier maintenance without needing to shut down the entire facility. These are usually found in heavy-duty environments where multiple motors need to run for various purposes.
Key Features of Low Voltage Switchboards
Structural Features
Most low voltage switchboards come in specialised enclosures, which may be freestanding or wall-mounted depending on specific requirements, including spatial limitations and protection ratings (such as ingress protection, or IP, ratings) to shield their components. This feature protects delicate components from accelerated wear and tear due to environmental exposure or damage.
Design Flexibility
Low voltage switchboard enclosures can be customised to meet tailored specifications, allowing you to fulfil your facility’s power needs. That customisation may also extend to its core components and their connections, as well as improving overall accessibility to facilitate maintenance work.
Energy Efficiency
As part of their electricity regulation function, low voltage switchboards also enhance energy efficiency by ensuring the appropriate electrical load is distributed to the right circuits. This also helps to maintain overall electrical grid safety by minimising the risk of short circuits or overloads due to poor electrical distribution and management.
Safety Measures
Circuit breakers or fuses are the primary safety measures in a low voltage switchboard, designed precisely to respond to sudden changes in electrical flow that could cause overheating or a short circuit. The immediate cut-off ensures your delicate equipment and machinery are protected from significant damage.
The Benefits of Low Voltage Switchboards
Proper implementation of low voltage switchboards can ensure your operations can continue uninterrupted while minimising costly maintenance expenses and downtimes.
Effective Power Distribution
Low voltage switchboards are the primary gateway for your commercial or industrial facility’s power needs, efficiently distributing it across the entire facility’s connected electrical equipment and machinery. By meeting stringent safety standards and using high-quality materials, the switchboard will be able to perform optimally and ensure your facility’s operations run smoothly while minimising maintenance downtime.
Power Efficiency
Long-term energy efficiency has become a vital point for any industry, and low voltage switchboards can provide this through various means. For one, digital modules allow for constant monitoring and control of the switchboard’s functions, granting improved operational efficiency that can yield significant savings. These new tools also ensure you can stay on top of electrical inefficiencies or potential issues before they worsen, thereby preventing energy wastage, disruptions to daily operations, and costly repairs.
Improved Electrical Safety
The introduction of many innovations to low voltage switchboards, ranging from advanced heat mitigation materials to optimised circuit layouts, has contributed towards enhanced electrical safety. These safety measures help to ensure the well-being of your personnel and minimise the risk of substantial infrastructure damage that could lead to hefty maintenance costs. Regular checks will also help to improve the long-term reliability and safety potential of these switchboards, which will pay dividends over time.
Easy Maintenance
Advances in switchboard technology ensure that regular, preventive maintenance can be carried out with minimal difficulty and help you stay ahead of potential issues before they worsen. The availability of custom enclosures and switchboard solutions also gives you plenty of versatility in how your switchboards operate and are maintained, giving you greater control and faster maintenance results when resolving electrical grid complications.
