Glossary

• Flat Wire: SPT: Stranded, Parallel, Thermoplastic
  This is always followed by a -1, -2 or -3, signifying insulation thickness for different applications.
• HPN: Heater, Parallel, Neoprene
  Required for heater-type application, such as irons, toasters, etc.
  NOTE: Electri-Cord can run some 20 AWG, but mostly we run 18, 16 and 14 AWG, 2 or 3 conductors.
• P = Parallel Wire (Flat).

Jacketed Wire:

• S = Stranded (or Service Wire)
• J = Junior Service (300 Volt). If no “J” is in the wire type, then it is a hard service (600 Volt).
• T = Thermoplastic. If no “T” is in the wire type, then it has a rubber jacket.
• O = Oil-Resistant Compound
• W = Weather-Resistant Compound
• V = Vacuum (as in vacuum cleaner). This is a small O.D. jacketed wire, very flexible and initially used for vacuum cleaners but now used on many different types of products. Available only in 18 AWG.

Examples:

• SV = Stranded Vacuum Rubber Jacketed (NO “T”)
• SJT = Stranded Junior Thermoplastic
• SJTOW = Stranded Junior Thermoplastic, Oil and Weather resistant for UL and CSA.

Miscellaneous requirements:

• S.P. = Surface Printed
• N.M. = Non-Migratory compound to prevent the wire color from bleeding under unusual circumstances.
• VW-1 = Vertical Flame test (formerly FR-1)
• IEC, ICC = International Color Code on the inner conductors (Blue, Brown, Green w/Yellow Stripe)
• N.A. = North American Color Code on the inner conductors (Black, White, Green)
• 41/34 = Stranding specification format (41 strands of 34 AWG wire for each inner conductor)
• T.C. = Tinned Copper inner conductors
• RIBBED = Outer jacket is striated with ribs
• R/S or W/S = Red or White Stripe for visual polarity inspection on Flat wire

Temperature Ratings:

• 60°C = Standard rating (except HPN =90°C)
• 105°C = Electri-Cord’s alternate rating
  (we normally don’t stock 75°, 90°C)
