Insulation
Okonite-FMR is Okonite's trade name for its heat resistant, mechanically rugged black pigmented ethylene-propylene base insulating compound.

Applications
Okonite-FMR Type RHH or RHW-2 600 Volt Power and Control Cables are recommended for general low voltage power and control applications. Okonite-FMR flame retardant insulated power cables may be used in generating plants, either nuclear or fossil fueled, substations and industrial plants. Type RHH or RHW-2 may be used up to 90°C in dry or wet locations. These cables may be installed in wet or dry locations, indoors or outdoors, in raceways, underground ducts, cable tray (size 1/0 AWG and larger per NEC 318-3) or lashed to a messenger for aerial installation.

Specifications

Ampacities

(1) Ampacities are based on Table 310-16 of the National Electrical Code for these 90°C rated conductors at an ambient temperature of 30°C. The 75°C wet column is provided for additional information.

The ampacities shown apply to open runs of cable, installation in any approved raceway, direct burial in the earth, or as aerial cable on a messenger. Derating for more than three current carrying conductors within a raceway is in accordance with Note 8 to NEC Tables 310-16 through 310-19.

(2) Based on three (3) conductors in a single enclosed or exposed conduit. Capacities based on 40°C air ambient using ICEA methods. For 30°C ambient multiply values by 1.10; for 50°C multiply by .90. For other ambients or installation conditions refer to Engineering Data Book EHB-90.

The ampacities shown also apply to cables installed in cable tray in accordance with NEC Section 318-11.
