 Meltric Code Compliance

The NEC requires motors to have readily accessible “line of sight” disconnects that are either an approved switch or a properly rated plug and receptacle. With their unique ability to withstand high in-rush currents, Meltric Decontactor™ Series plugs and receptacles are the perfect choice for the line of sight disconnect required on motors and other inductive loads. DS, DSN and DB Decontactors are horsepower rated and pass testing at the 6xFLA current level required relative to locked rotor conditions.


NFPA 70E requires that any person working near live parts must wear protective clothing and equipment based on the calculated incident energy exposure level or alternatively on NFPA’s listed minimum requirements.
Once installed, Meltric Decontactor Series plugs and receptacles simplify compliance to NFPA 70E requirements. Their dead front construction eliminates the possibility of access to live parts so there is no need to don personal protective equipment when changing out motor or other equipment connected with Meltric Decontactors.

OSHA Construction Standard 1926.404 ~ Wiring Design and Protection for Construction Sub part K of the 29 Code of Federal Regulations (CFR):

1926.404 (b)(l)(ii)
All 120V, single-phase 15A and 20A receptacle outlets on construction sites, which are not a part of the permanent wiring of the building or structure and which are in use by employees, shall have approved ground fault circuit interrupters for personal protection. Receptacles on a two-wire, single-phase portable or vehicle mounted generator, rated not more than 5KW, where the circuit conductors of the generator are insulated from the generator frame and all other ground surfaces need not be protected with ground fault circuit interrupters.

1926.404 (b)(l)(iii)
The employer shall establish and implement an assured equipment grounding conductor program on construction sites covering all cord sets, receptacles which are not a part of the building or structure and equipment connected by cord and plug which are available for use or used by employees. The program shall comply with the following minimum requirements:


1926.404 (b)(l)(iii)(A)
A written description of the program, including the specific procedures adopted by the employer, shall be available at the job site for inspection and copying by the Assistant Secretary and any affected employee.

1926.404 (b)(l)(iii)(B)
The employer shall designate one or more competent persons (as designed in 1926.32(f)) to implement the program.

1926.404 (b)(l)(iii)(C)
Each cord set, attachment cap, plug and receptacle of cord sets, and any equipment connected by cord and plug, except cord sets and receptacles which are fixed and not exposed to damage, shall be visually inspected before each day’s use for external defects such as: deformed or missing pins, insulation damage, or indications of possible internal damage. Equipment found damaged or defective shall not be used until repaired.
