Main Features of the JCMCU Metal Consumer Unit

Available in Multiple Way Sizes (4, 6, 8, 10, 12, 14, 16, 18, 22 Ways)

The JCMCU Metal Consumer Unit comes in various sizes to accommodate different electrical load requirements. It is available in 4, 6, 8, 10, 12, 14, 16, 18, and 22 usable ways. This wide range of options allows you to choose the appropriate size based on the number of circuits you need to distribute power to in your residential or commercial setting.

IP40 Degree of Protection

These consumer units have an IP40 degree of protection rating. The “IP” stands for “Ingress Protection,” and the number “40″ indicates that the enclosure provides protection against solid objects larger than 1mm in size, such as small tools or wires. However, it does not protect against water or moisture ingress. This rating makes the JCMCU Metal Consumer Unit suitable for indoor installations where it is not exposed to liquids or excessive moisture.

Compliance with 18th Edition Wiring Regulations

The JCMCU Metal Consumer Unit complies with the 18th Edition of the Wiring Regulations, which are the latest industry standards for electrical installations in the UK. These regulations ensure that the consumer unit meets strict safety requirements for overload and surge protection, providing a high level of safety for your electrical system.

Non-Combustible Metal Enclosure (Amendment 3 Compliant)

The consumer unit features a non-combustible metal enclosure, making it compliant with Amendment 3 of the Wiring Regulations. This amendment requires consumer units to be constructed from non-combustible materials, such as metal, to reduce the risk of fire and improve overall safety.

Surge Protection Device (SPD) with MCB Protection

The JCMCU Metal Consumer Unit comes equipped with a Surge Protection Device (SPD) at the incoming supply. This SPD helps protect your electrical system from damaging voltage surges caused by lightning strikes or other electrical disturbances. Additionally, the SPD is protected by a Miniature Circuit Breaker (MCB), which enhances the overall safety and reliability of the system.

Top-Mounted Earth and Neutral Terminal Bars

The earth and neutral terminal bars are conveniently located at the top of the consumer unit. This design feature makes it easier for electricians to connect the earth and neutral conductors during installation, improving the overall efficiency and safety of the wiring process.

Surface Mounting Capability

These consumer units are suitable for surface mounting, which means they can be installed directly onto a wall or other flat surface. This installation method is often preferred in retrofit situations or when concealed wiring is not an option, as it provides easy access to the unit for maintenance or future modifications.

Front Cover with Captive Screws

The front cover of the JCMCU Metal Consumer Unit features captive screws, which are screws that remain attached to the cover even when loosened. This design prevents the screws from falling out or getting lost during installation or maintenance, making the process more convenient and efficient.

Fully Enclosed Metal Construction with Drop-Down Metal Lid

The consumer unit has a fully enclosed metal construction body with a drop-down metal lid. This robust design provides excellent protection for the internal components, shielding them from physical damage, dust, and other environmental factors.

Multiple Cable Entry Knock-Outs

The JCMCU Metal Consumer Unit offers multiple circular cable entry knock-outs on the top, bottom, sides, and back. These knock-outs have diameters of 25mm, 32mm, and 40mm, allowing for easy cable entry and routing. Additionally, there are larger rear slots for accommodating larger cables or conduits.

Raised Key Holes for Easy Installation

The consumer unit features raised key holes, which make it easier to securely mount the unit onto a wall or surface. These raised key holes provide a stable and secure installation, ensuring that the unit remains firmly in place even after years of use.

Raised Din Rail for Improved Cable Routing

Inside the consumer unit, the Din rail (where the circuit breakers and other devices are mounted) is raised, creating additional space for better cable routing and organization. This design feature improves the overall neatness and accessibility of the wiring within the unit.

White Polyester Powder Coating

The JCMCU Metal Consumer Unit has a modern style finish with a white polyester powder coating. This coating not only provides an attractive appearance but also offers excellent resistance to corrosion, scratches, and other types of wear and tear, ensuring a long-lasting and durable finish.

Large and Accessible Wiring Space with Extra RCBO Space

The consumer unit offers a large and accessible wiring space, making it easier for electricians to work within the unit during installation or maintenance. Additionally, there is extra space provided specifically for accommodating Residual Current Circuit Breakers with Overload Protection (RCBOs), which offer both overcurrent and residual current protection in a single device.

Flexible Connection Options

The JCMCU Metal Consumer Unit allows for various configurations of protected ways, providing flexibility in how you distribute and protect your electrical circuits. This feature enables you to tailor the consumer unit to meet the specific needs of your residential or commercial application.

Main Switch Incomer Option

Some models of the JCMCU Metal Consumer Unit are available with a main switch incomer, which serves as the primary disconnect point for the entire electrical system. This option can be useful in certain installations where a dedicated main switch is required or preferred.

RCD Incomer Option

Alternatively, the consumer unit can be configured with a Residual Current Device (RCD) at the incoming supply. This RCD provides protection against electrical shocks and fires caused by earth faults or leakage currents, enhancing the overall safety of the electrical system.

Dual RCD Populated Option

For applications that require additional levels of protection, the JCMCU Metal Consumer Unit can be populated with dual RCDs. This configuration provides redundancy and increased safety, ensuring that even if one RCD fails, the other will still provide protection against earth faults and leakage currents.

Maximum Load Capacity (100A/125A)

The JCMCU Metal Consumer Unit can accommodate maximum load capacities of up to 100 amps or 125 amps, depending on the specific model and configuration. This load capacity makes it suitable for a wide range of residential and commercial applications with varying power demands.

Compliance with BS EN 61439-3

Finally, the JCMCU Metal Consumer Unit complies with the BS EN 61439-3 standard, which specifies the requirements for low-voltage switchgear and controlgear assemblies intended for use in power distribution and motor control applications. This compliance ensures that the consumer unit meets rigorous safety, performance, and quality standards set by the British Standards Institution (BSI).

The JCMCU Metal Consumer Unit is a robust and versatile electrical distribution system that offers comprehensive protection and safety features. With its multiple size options, compliance with the latest regulations, surge protection, and flexible configuration possibilities, it provides reliable power distribution for both residential and commercial applications. Its durable metal construction, easy installation, and accessible design make it a practical and efficient choice for ensuring safe and efficient electrical power management.
