(i) Halogen Free Appliance Cords and Cables

Concern for the environment has increased in recent years and there has been growing demand for greater attention to environmental protection. As a leader in the power cord industry, Chau¡¦s Electrical Co., Ltd. is taking the lead by using Green Materials in our products. Initial R&D projects removed heavy metals, and now we have developed a line of Halogen-Free Appliance Cords, Cables and Power Cords to meet new industry demands.


EM cables for Japanese market

The Japanese market is moving toward EM (Ecology Material) cable as a replacement for traditional PVC cable. The new EM cable is more environmentally friendly and specifically it is halogen-free.
The EM cables used for power cords are as follows:


PVC cable type EM cable type EM cable standard PVC cable standard
VSF/HVSF EM-ESF
EM-CSF
JCS 4501-2002 Flame and Heat
retardant polyethylene cord.
(excluding heat retardant cross

It has been investigated for outdoor use, in wet locations, such as for low voltage landscape lighting (LVLL) or golf course sprinkler systems (GCS) or lawn sprinkler systems (LSS) or similar purpose.

  • Construction: Single, two or three insulated conductors laid parallel
  • Conductors: Nos. 8, 10, 12, 14, 16 or 18 AWG, solid or stranded, bare copper.
  • Features: Sunlight resistant, Water resistant, Low temperature classification ¡§-40¢J¡¨ , Direct burial
  • UL listed File no: E253413
  • CSA certification no: LL85350



(iii) Next generation Plugs with AFCI devices for Household Appliances


The purpose of AFCI devices is for protection of human life and to prevent cord fires. It will be used in the next generation power supply cord for home appliances. In America, problems in home wiring, like arcing and sparking, are associated with more than 40,000 home fires each year. These fires claim over 350 lives and injure 1,400 victims annually. A new electrical safety device for homes, called an arc fault circuit interrupter or AFCI, is expected to provide enhanced protection from fires resulting from these unsafe home wiring conditions. Typical household fuses and circuit breakers do not respond to early arcing and sparking conditions in home wiring. By the time a fuse or circuit breaker opens a circuit to defuse these conditions, a fire may already have begun.
Several years ago, a CPSC study identified arc fault detection as a promising new technology. Since then, CPSC electrical engineers have tested the new AFCI¡¦s on the market and found these products to be effective.


  • Definitions

    AFCI---Arc-Fault Circuit-Interrupter.
    In 210.12(A), 2002 NEC defines an AFCI as ¡§a device intended to provide protection from the effects of arc faults by recognizing characteristics unique to arcing and by functioning to de-energize the circuit when a arc fault is detected¡¨


  • Background

    (a) AFCIs are already recognized for their effectiveness in preventing fires. The most recent edition of the National Electrical Code, the widely-adopted model code for electrical wiring, requires AFCIs for bedroom circuits in new residential construction, effective January 2002.
    Future editions of the code, which is updated every three years, could expand coverage.
    (b) Effective January 1, 2002, NFPA 70, The National Electrical Code (NEC), Section 210-12, requires that all branch circuits supplying 125V, single phase, 15- and 20-ampere outlets installed in dwelling unit bedrooms be protected by an Arc-Fault Circuit Interrupter. AFCI devices have been mandated by the National Electric Code and UL for the cord sets on room air conditioners beginning in August 2004. The standard is UL484 that comply with the requirements on paragraph 440.65 of NEC 2000.

    ¡§Single phase cord and plug connected room air conditioners shall be provided with factory installed LCDI* or AFCI protection. The LCDI* or AFCI protection shall be an integral part of the attachment plug or be located in the power supply cord within 12 in. of the attachment plug.¡¨
    Remark: LCDI is the abbreviation for Leakage-Current Detector-Interrupters.
