FAQ

Questions engineers ask first

Not covered here? Send your drawing — an engineer replies within 2 business hours.

What do Type E2, Type E4 and Type E5 designate under MGM 112?
In the MGM 112 underground mining specification, the 'E' series covers 660/1,100 V steel-wire-armoured rubber cables without individual metallic screens on the cores: Type E2 is a 2-core cable for lighting and single-phase auxiliaries; Type E4 is a 4-core cable (3 phase + 1 earth); and Type E5 is a 5-core cable (3 phase + 1 earth + 1 pilot or neutral core).
How does MGM 112 Type E2 / E4 / E5 differ from Type 62 / 63 / 64?
Type 62, Type 63 and Type 64 have an individual copper/nylon composite earth screen braided around each live core inside the pliable wire armour. Type E2, Type E4 and Type E5 have unscreened EPR-insulated cores protected collectively by the elastomeric inner bedding and outer galvanised steel wire armour.
Why is Type E5 (5-core) widely used on gate-end and conveyor drives?
Type E5 provides three phase conductors, one full-size protective earth conductor and one dedicated 5th pilot/interlock conductor in a single armoured cable, allowing remote start/stop or earth-continuity interlock loop wiring without pulling a separate control cable.
Can Type E2 / E4 / E5 be used in wet underground galleries?
Yes. The tinned Class 5 copper conductors, GP8 EPR insulation, vulcanised rubber inner bedding and heavy-duty polychloroprene (PCP) outer jacket are engineered for wet, oily and abrasive underground mine roadways.
