50 amp Cord

It's partially the jacket but mostly the wire itself. A single strand of #6 wire is hard to bend. A multiple strand wire is easier to bend. The more strands there are in that make up the 6ga conductor the more flexible it is.

For example 6ga superflex welding cable has 266 strands. A listing on Ebay showed a 6/4 cable with each wire having 133 strands. It would be stiffer than the welding cable.


Understanding SO Cord Designations

What do all SO Cord letter designations stand for? See the table below for a simple breakdown.

Designation What this means
S Service grade. Extra hard service when not followed by J, P, or V.
J Hard service
V Vacuum cleaner cord and light duty cable.
P Parallel cord (also known as zip cord). Light duty only.
E Thermoplastic Elastomer (UL/NEC designation only)
O Oil resistant*
T Thermoplastic
W Outdoor. Sunlight-resistant jacket, wet location rated conductors. Formerly "W-A".
H Heater cable
VW-1 Flame retardant
FT2 Flame retardant

* When one "O" is in a designation (for example, "SJOW"), only the outer jacket material is oil resistant. If there are two "O's" are in the classification (such as "SOOW"), both the outer jacket and conductor insulation are oil resistant.
