BS 5550-7.5.4 discusses cinematography, production, presentation, film and television location lighting with a focus on specifications for single-pole high current plugs and socket connectors. BS 5550-7.5.4 is the seventh part of the BS 5550 multi-series on cinematography that specifies requirements for single-pole power outlets, cable sockets, cable couplers, and appliance couplers (these are all referred to generally throughout the standard as accessories).
The accessories are for use on a.c. supplies with a voltage to earth not exceeding 250 V and a frequency not exceeding 500 Hz and on 120 V d.c. supplies. Two sizes are specified, rated at 150 A and 400 A respectively. The accessories are intended for use in the television industry for lighting purposes “on location” either indoors or outdoors. The accessories are intended for continuous use in ambient temperatures between – 20 °C and + 35 °C.
BS 5550-7.5.4 on specifications for single pole high current plugs and socket connectors is useful for:
Accessories are designed and constructed so that in normal use their performance is reliable and without danger to the user or surroundings. The accessories are of two non-interchangeable sizes with maximum current ratings of 150 A and 400 A respectively and they are of splashproof design.
BS 5550-7.5.4 discusses general requirements, general notes on tests, standard rating, classification, dimensions, protection against electric shock, terminals and terminations, retaining device, resistance to ageing of rubber, moisture resistance, insulation resistance and electric strength, normal wear and tear, temperature rise, mechanical strength, resistance to heat, fire, and tracking, and resistance to rust.
The requirements provided by BS 5550-7.5.4 assist you in improving the performance and quality of the single-pole high current plugs and socket connectors and ensuring protection against electric shock.
With obedience and compliance to BS 5550-7.5.4, you can enhance single-pole high current plugs and socket connectors’ effectiveness and efficacy and manufacture a standardized product.
