What is a Power Board?

A power board is a device that provides multiple electrical sockets for connecting various appliances simultaneously. It typically includes a surge protector to safeguard connected devices from power spikes. Power boards are commonly used in households and offices to extend the capability of a single electrical outlet.

When considering a power board, it’s important to note that they come in various designs and capacities. Professional Mackay electricians know they cater to different power requirements and safety standards.

In this blog, we’ll discuss the role, main parts, and common questions regarding power boards.

What is the Role of a Power Board?

The role of a power board is to expand the number of available electrical outlets, allowing multiple devices to be powered from a single source. It is a practical solution in areas where the number of built-in electrical outlet points is insufficient for the user’s needs.

Power boards are particularly useful in office settings, workshops, and home entertainment areas. These locations often have the highest demand for electrical connections, often exceeding the number of available wall outlets.

In addition to providing extra sockets, power boards often incorporate safety features such as surge protection. This feature guards connected devices against voltage spikes that can occur during electrical storms or power surges.

Some models also include capabilities like individual switches for each socket, allowing for greater control over the power supply to each connected device. This versatility and the added layer of protection make power boards a critical tool in managing electrical safety and efficiency in various settings.

4 Main Parts of a Power Board

The following are the 4 main parts of a power board:


The outlets are the primary component of a power board, providing multiple sockets for plugging in various electrical devices. These outlets are designed to accommodate standard plugs and are arranged to allow easy access. The number and spacing of these outlets can vary, with some power boards offering additional spacing for larger adaptors or transformers.

On/Off Switch

The on/off switch on a power board offers a convenient way to control the power supply to all connected devices. This switch allows users to turn off all devices at once, helping conserve energy and reducing the risk of electrical hazards when the sockets are not in use. Some power boards feature individual switches for each outlet for even greater control.

Circuit Breaker

A circuit breaker is a crucial safety feature in a power board. It automatically cuts off the electrical flow if an overload is detected, preventing damage to connected devices and reducing the risk of fire. This component is essential for maintaining safe operation, especially when multiple devices are drawing power simultaneously.

Power Cord

The power cord connects the power board to the main electrical supply. It is typically a heavy-duty cable designed to handle the maximum current the power board is rated for. The length of the power cord can vary, providing flexibility in positioning the power board relative to the electrical outlet.

Can I Plug Any Appliance Into a Power Board?

No, not all appliances can be plugged into a power board. Certain devices like air conditioners and refrigerators should not be connected to a power board. This is to prevent overloading, potential fire hazards, or damage to the appliance and power board.

Besides the ones mentioned above, the following lists other appliances that you shouldn’t plug into a power board:

  • Freezers: Due to their continuous operation and high power usage, it’s safer to plug these appliances directly into a wall outlet.
  • Microwaves: The high electricity draw for heating purposes makes microwaves unsuitable for power boards.
  • Washing Machines and Dryers: Their high power consumption and constant use make them inappropriate for power boards.
  • Dishwashers: As with washing machines, the power requirement and duration of use make dishwashers unsuitable for power board connections.

What Can I Plug Into a Power Board?

You can plug low to medium power consumption devices into a power board, such as laptops, phone chargers, lamps, and small kitchen appliances like toasters or blenders. Make sure the total power draw of all connected devices does not exceed the power board’s capacity.

Always check the individual appliance’s power requirements and the power board’s rating to ensure safe usage.

Is It Safe to Plug a Power Board Into Another Power Board?

No, it is not safe to plug a power board into another power board. This practice, often called ‘daisy chaining’ or ‘piggybacking,’ can overload the electrical circuit, increasing the risk of an electrical fire.
