Appleton™ and O-Z/Gedney™ Liquidtight Connectors are suitable for use in the following hazardous locations:

• Class I Division 2 per NEC 501.10(B)(2)

• Class I Zone 2 per NEC 505.15(C)(2)

• Class II Division 1 per NEC 502.10(A)(2)

• Class II Division 2 per NEC 502.10(B)(2)

• Class III Division 1 per NEC 503.10(A)(3)

• Class III Division 2 per NEC 503.10(B)

• Intrinsically Safe Systems per NEC 504.20

• Bonding locknuts are recommended when installed in slipholes

• LFMC shall include a wire-type Equipment Bonding Jumper per NEC 501.30(B), 502.30(B)and 503.30(B)

Where flexibility is not required, LFMC is suitable as a ground return path under the following conditions (reference NEC 350.60):

• Per NEC 250.118(6)(a), the conduit is terminated in listed fittings (i.e. Appleton™ ST and O-Z/Gedney™ 4Q and LM Series)

• Per NEC 250.118(6)(b), trade sizes 3/8” and 1/2” contain conductors protected by max 20 amp overcurrent protection

• Per NEC 250.118(6)(c), trade sizes 3/4” to 1-1/4” contain conductors protected by max 60 amp overcurrent protection

• Per NEC 250.118(6)(d), the ground fault current path does not exceed 6 feet

• Larger sizes and/or higher overcurrent protection will require an equipment grounding conductor (EGC)
Appleton™ ST-L and STB-L, O-Z/Gedney™ 4Q-LT and 4Q-FML are recommended for connection to maximum 6 foot external equipment grounding conductor (EGC) per NEC 250.102(E)(2).
Where flexibility is required after installation to allow movement or minimize vibration, an equipment grounding conductor (EGC) must be installed per NEC 250.118(6)(e).
