UL67 PanelBoards

UL67: UL 67-Safety Basis for PanelBoards

In the field of terminal power distribution of Building Electricity and Industrial Facilities, distribution board is ultimate and essential security defensive line of terminal circuit. UL67 is authoritative principles for field-installed distribution board. Since we obtain UL Factory Certification in 2014, we consistently integrate core element of UL67 into design & manufacture of LV Switchboard, and dedicate to provide safety and trustworthy solutions of power distribution for various terminal power distribution application.

A, What is UL67?

UL67 is the standard for field-installed distribution boards developed by UL. It applies to PanelBoards normally rated at 600V AC/DC or less and intended for assembly of circuit breaker, fuse, switch and protective & control components.

UL67 Core Orientation:

· UL67 Standard is the specification of commonest and widely-used PanelBoards intended for building.

· UL67 Standard place emphasis on structural safety of enclosure and basic safety of assembled distribution board.

· UL67 Standard is to guarantee effective protection from building office, workshop, residential building through to terminal of routine electricity usage.

In brief, LV Distribution Board with UL67 Certification is “Security Guard” to guarantee terminal circuit safety and eliminate local electrical fault.

B, UL67 Core Requirement illumination- Dedication to Minutiae

1. Structure and Material of Enclosure

o Requirement: Enclosure fabrication must utilize sufficient mechanical strength of durable material to protect internal components, and have different IP rating depending on the installation environment (e.g., dry or humid).

o Exhibition of Professional: Our LV Switch Board utilize superior galvanized steel and flame retardant plastics to eliminate risk of enclosure deformation and damage, and provide internal components secure physical protection during shipping, installation and long-term operation.

2. Internal Layout and Safe Wiring

o Requirement: Enclosure must have sufficient wiring space, and smooth & well-rounded edge to guarantee wire smoothly pass in a sheet metal wall within the enclosure, and reduce the risk of abrasion of the insulation.

o Exhibition of Professional: We scientifically design internal layout, provide sufficient wiring space, and crimp and deburr the edge of metal to prohibit the potential risk due to improper installation.

3. Installation and Compatibility of Components

o Requirement: Enclosure must safely and tightly install circuit breaker, fuse, etc., equipped with UL certification. Strength and compatibility of mounting support (e.g. rail) must be verified.

o Exhibition of Professional: Our distribution board is equipped with mounting rail and accurate mounting hole to guarantee perfect compatibility and secure mounting with components

4. Clearance and Grounding

o Requirement: Specify minimum clearance between live parts of different potential or live parts and grounding metal. Enclosure must provide effective grounding terminal.

o Exhibition of Professional: We comply with the requirements of clearance and creepage distance to equip with clear and reliable grounding terminal.

5. IP Rating and Mark

o Requirement: Distribution Board must provide clear and permanent UL mark, and label with critical rated information such as rated voltage, rated current, short-circuit current rating (SCCR), IP rating depending on the installation environment.

o Exhibition of Professional: We provide distribution board of various IP rating, and guarantee each distribution board is equipped with UL Certification Mark. This is straightforward basis for you to identify qualified products.

C, Why is distribution board with UL67 certification essential?

A seemingly simple Distribution Board is indispensable part of electrical safety system. Choosing LV distribution board with UL67 Certification Mark represents:

· Prohibit Local Risk: Qualified distribution board is able to prohibit electric shock, arc, short-circuit, and occurrence and expansion of electrical fault.

· Compatibility Assurance: It is able to guarantee safety and stable operation of circuit breaker, residual current devices, etc., under designed environment.

· Quality and Obligation: As UL Certification Factory, we guarantee consistency and traceability of product to eliminate the risk of legal liability and insurance due to use of non-certified products.

· Long-term and Reliable Operation: We implement assessment from material to process to guarantee durability during product life cycle.

UL67 standard may be dedicated to the most basic components of electrical system, however, this ultimate dedication to basic safety builds the solid basis of entire electrical system. As UL Certification Factory, we have profound comprehension of “A small leak will sink a great ship”. We commit each deliverable distribution board is carrying complying with UL67 Standard and ultimate responsibility for end-user.

Our professional standard and reliable product guarantee your terminal of electricity usage
