What is a Danson Consumer Unit?
A Danson consumer unit is an electrical distribution board used in residential and commercial buildings to distribute electrical power to various circuits and appliances. It is a type of electrical panel that contains circuit breakers, which protect the electrical circuits from overloading and short circuits.
Danson consumer units are designed to be compact, easy to install and use, and to comply with the latest electrical safety regulations.
Danson consumer units come in different sizes and configurations, depending on the number of circuits and the power requirements of the building. They can also be equipped with various accessories such as surge protection devices, residual current devices (RCDs), and time switches to enhance the safety and functionality of the electrical system.
It is important to have a qualified electrician install and maintain a Danson consumer unit, as working with electricity can be dangerous and requires proper training and expertise.
What is a Danson RCD?
A Danson RCD (Residual Current Device) is an electrical safety device that is designed to protect people from electric shock caused by faulty wiring or appliances. It is also commonly known as an RCCB (Residual Current Circuit Breaker).
A Danson RCD works by monitoring the electrical current flowing through a circuit and detecting any imbalances between the live and neutral wires. If a fault is detected, such as an electrical current leaking to the ground or through a person, the Danson RCD will quickly switch off the power supply to prevent any potential harm.
Danson RCDs are available in different sensitivity ratings, depending on the type of application and the level of protection required. They are typically installed in electrical distribution boards or consumer units, either as standalone devices or combined with circuit breakers and other protective devices.
It is important to regularly test Danson RCDs to ensure they are functioning correctly, as they can deteriorate over time or become damaged due to electrical surges or faults. If a Danson RCD is found to be faulty or defective, it should be replaced immediately by a qualified electrician to ensure the safety of the electrical system and its users.
What is a Danson MCB?
A Danson MCB (Miniature Circuit Breaker) is an electrical switch that automatically switches off the electrical supply in case of an overload or short circuit in the circuit it is protecting. It is a type of circuit breaker that is designed to protect electrical circuits from damage and prevent electrical fires.
Danson MCBs are used in electrical distribution boards or consumer units to protect individual circuits or appliances from overloading. They are designed to trip and switch off the power supply automatically when the current exceeds the rated current of the MCB.
Danson MCBs are available in different current ratings, ranging from a few amps to several hundred amps, depending on the application and the power requirements of the circuit or appliance. They are typically color-coded to indicate their current rating and are easy to install and operate.
It is important to select the correct Danson MCB for the application and to regularly test and maintain them to ensure they are functioning correctly. If an MCB is found to be faulty or defective, it should be replaced immediately by a qualified electrician to prevent any potential damage or harm.
What is an RCBO
An RCBO (Residual Current Circuit Breaker with Overcurrent Protection) is an electrical safety device that combines the functions of a residual current device (RCD) and a miniature circuit breaker (MCB) into a single unit.
The RCD function of an RCBO detects earth leakage faults that can occur due to a fault in an electrical device or wiring, which can cause electric shock hazards. The MCB function of an RCBO detects and protects against overcurrent faults, such as those caused by short circuits or overloading of electrical circuits, which can cause damage to electrical equipment and can create a fire hazard.
An RCBO is installed in the electrical distribution board or panel, and it can protect individual circuits or specific devices within a circuit. If an electrical fault occurs, the RCBO will trip and disconnect the circuit from the power supply to prevent electrical shock or damage to the equipment.
The benefits of using an RCBO include increased safety, space-saving design, and flexibility in a variety of applications. RCBOs are commonly used in residential, commercial, and industrial installations to provide comprehensive electrical protection for people and equipment.
What is an MCB
An MCB, which stands for Miniature Circuit Breaker, is used to protect an electrical circuit from overloading and short-circuiting. It is a type of electrical switch that automatically trips or shuts off the circuit when the current flowing through it exceeds a certain limit.
MCBs are commonly used in residential and commercial buildings to protect electrical wiring and appliances from damage due to electrical faults. They are installed in the electrical distribution board or panel, and each MCB is rated to protect a particular electrical circuit.
In the event of an electrical fault, such as an overload or short circuit, the MCB trips, and the circuit is disconnected from the power supply. This helps prevent damage to the electrical wiring and appliances, as well as the risk of electrical fires.
Compared to traditional fuses, MCBs are faster and more reliable in responding to electrical faults. Additionally, MCBs can be easily reset after tripping, whereas fuses need to be replaced.
Difference between an RCD and an RCBO
The main difference between an RCD and an RCBO is that an RCD only provides protection against electrical shock, while an RCBO provides protection against both electrical shock and overcurrent. Additionally, an RCBO is more expensive than an RCD, as it contains both RCD and MCB components.
When choosing between an RCD and an RCBO, it is important to consider the specific requirements of the application. For example, an RCBO may be more suitable for applications where protection against overcurrent is critical, such as for sensitive electronic equipment or machinery.
RCD stands for Residual Current Device, while RCBO stands for Residual Current Circuit Breaker with Overcurrent Protection. While both devices offer protection against electrical hazards, there are some important differences between them.
An RCD is a safety device that is designed to protect against electrical shock caused by current leakage. It works by constantly monitoring the current flowing through a circuit and quickly disconnecting the power supply if it detects a current imbalance, such as when current is flowing through a person or an unintended path to earth.
An RCBO, on the other hand, is a combination of an RCD and a miniature circuit breaker (MCB). It provides both protection against electrical shock and protection against overcurrent, such as from an electrical overload or short circuit. Like an RCD, an RCBO monitors the current flowing through a circuit and disconnects the power supply if it detects a current imbalance. Additionally, it can also trip in the event of an overcurrent, providing a double layer of protection.

Best Electric Patio Heater?
The choice between a wall-mounted or freestanding patio heater depends on various factors, including your specific needs, space availability, aesthetics, and practical considerations. Here are some points to consider for each type:
Wall-Mounted Patio Heater:
Wall-mounted patio heaters are fixed directly onto a wall or a sturdy vertical surface, which saves floor space. This can be advantageous if you have limited space on your patio or deck.
Wall-mounted heaters offer a sleek and streamlined appearance since they are mounted flush against the wall. They can blend well with the overall design of your outdoor space without taking up much visual space.
Wall-mounted heaters generally emit heat in a more targeted and focused manner. They provide localized warmth, making them suitable for specific seating areas or spaces where people tend to gather.
Since wall-mounted heaters are securely attached to a fixed surface, they provide stability and eliminate the risk of tipping or falling over. This can be beneficial in windy conditions or high-traffic areas.
Freestanding Patio Heater:
Freestanding patio heaters offer greater mobility and flexibility. You can move them around easily to different locations based on your heating needs or to accommodate changes in seating arrangements.
Depending on the power and size of the freestanding heater, they can generally provide heat over a larger area compared to wall-mounted heaters. This can be advantageous if you have a spacious outdoor area or if you frequently host gatherings with larger groups.
Freestanding patio heaters come in various designs and styles, allowing you to choose the one that complements your outdoor décor. They often feature a visible flame or heating element, which can add ambiance to your outdoor space.
Freestanding heaters are typically easier to access for maintenance, refueling (in the case of propane or natural gas heaters), and adjusting heat settings. This convenience can be a factor to consider if you prefer easy accessibility for operation and maintenance purposes.
Ultimately, the choice between wall-mounted and freestanding patio heaters depends on your specific preferences, available space, and the desired functionality. You may also consider a combination of both types if you have different areas within your outdoor space that require heating.
