This 1.5mm² 4 core H07RN-F heavy duty rubber cable is a black, harmonised (HAR) flexible power cable supplied as a 100 metre coil. Each core uses EPR rubber insulation (EI4) over a Class 5 finely stranded bare copper conductor, finished in a tough black polychloroprene (neoprene) rubber sheath (EM2). The 4 cores are brown, black, grey and green/yellow earth (4G1.5), so one cable covers a single-phase supply with earth or a three-phase supply with earth.
Rated 450/750 V and oil resistant, UV resistant, ozone resistant and flame retardant (IEC 60332-1-2), H07RN-F is the standard choice for medium mechanical stress in dry, damp and wet locations, indoors and outdoors. Typical uses include power tools, site equipment, temporary supplies, portable machinery, motors, heating plant and industrial or agricultural connections. It is also permitted for fixed installation on plaster or machines and, when protected in conduit or equipment, up to 1000 V AC / 750 V DC.

Safety and regulations: Installation and connection must be carried out by a competent person in line with BS 7671 and, for domestic work, Part P. Current-carrying capacity depends on the installation method, ambient temperature and grouping, so always size the cable and its protective device to the load before use.
Good to know: This listing supplies one continuous 100 metre coil, ideal for multiple runs, site supplies and workshop stock. The cable carries the standard HAR H07RN-F marking, so you can confirm the type on the sheath on arrival.

Frequently Asked Questions
What does H07RN-F mean?
H = harmonised European standard, 07 = 450/750 V, R = rubber insulation, N = polychloroprene rubber sheath, F = flexible (finely stranded) conductor.
Can this cable be used outdoors?
Yes. The UV, ozone and weather resistant sheath suits outdoor use in dry, damp and wet locations. Protect it from sharp edges and sustained mechanical damage, and install it in line with BS 7671.
Which core colours does the 4 core version have?
The cores are brown, black, grey and green/yellow. The green/yellow core is the protective earth, which is why the cable is described as 4G1.5.
How tightly can I bend the cable?
Keep to a minimum bending radius of 4 x the outer diameter for fixed installation and 7.5 x the outer diameter for flexible use.
How much cable is supplied?
This listing is for one 100 metre coil of black 4 core 1.5mm² H07RN-F rubber cable. At roughly 17 kg, plan for safe manual handling when moving it.
