SJOOW Cable 300V Portable Power Cable

SJOOW cable is a flexible 300 V junior-service portable cord for indoor and outdoor power connections exposed to oil, water, moisture, weather and repeated handling. The supplied construction uses fully annealed stranded bare-copper conductors, colour-coded 90 °C EPDM insulation and an oil-resistant jacket.

The designation helps identify its intended construction: S means service cord, J denotes the junior 300 V class, the two O letters indicate oil-resistant insulation and an oil-resistant outer jacket, and W identifies weather- and water-resistant service. The supplied range covers 18 through 10 AWG, with two-, three- and four-conductor colour schemes shown in the Construction tab.

SJOOW is used for portable tools, small motors, pumps, appliances, extension assemblies and temporary industrial power where a flexible 300 V cord is appropriate. It is not a direct substitute for a 600 V cord: compare the SOOW 600 V portable power cable when the circuit or equipment requires the higher voltage class. Send the AWG size, number of conductors, required length, load current, plug or termination, environment, listing and marking requirements for a technical quotation.

SJOOW Cable Construction

Core Colour Code

Final stranding, insulation and jacket thickness, colour sequence, printing, outside diameter and weight are controlled by the quoted size and conductor count.

Applications

SJOOW portable cord is selected where a highly flexible 300 V cable must tolerate indoor or outdoor handling and exposure to oil, water, moisture, weather and sunlight.

• Portable hand tools and service equipment
• Small motors, pumps and appliances
• Indoor/outdoor extension-cord and temporary-power assemblies
• Workshops, construction support and industrial maintenance
• Equipment requiring a flexible junior-service cord

The supplied data describes good tensile strength, elongation and ageing characteristics together with high flexibility. Size the cable using equipment load, allowable ampacity, voltage drop, total circuit length, ambient conditions and termination ratings. The 10 A value shown in Specifications belongs to the supplied 18 AWG, two-conductor example and must not be applied to every SJOOW configuration.

SJOOW 300 V Specifications

Supplied 18 AWG Two-Conductor Example

The 0.285 in OD and 10 A value apply to the specific 18 AWG, two-conductor configuration shown in the supplied screenshot. Dimensions and ampacity change with AWG size, conductor count, installation, ambient temperature and applicable electrical rules.

SJOOW size and conductor-count range

Each size below is built in 2, 3, 4 and 5-conductor form. Where a run needs 600 V rather than the 300 V junior-service rating, the same sizes are available as SOOW.

Certification: UL 62 category ZJCZ Flexible Cord, certificate UL-US-2449012-4; CSA C22.2 No. 49 category ZJCZ7, certificate UL-CA-2437036-5. Product may be supplied bearing the UL Mark.

Ampacity, stranding and dimensions

Conductor stranding follows UL 62. Every size in the SJOOW range is bunch-stranded, which is what gives junior-service cord its handling characteristics at 300 V.

Read the two ampacity columns by current-carrying conductors, not by the number of cores in the cord. The 3-conductor column applies to a 3-conductor cord, and also to a 4-conductor cord where only three conductors carry current. The 2-conductor column applies to a 2-conductor cord, and to a 3-conductor cord where only two conductors carry current. An equipment grounding conductor does not count, and a neutral carrying only the unbalanced current of an otherwise balanced circuit does not count either.

Where four to six conductors do carry current, NEC 400.5 reduces each conductor to 80 percent of the tabulated value — a SOOW 12 AWG build with four current-carrying conductors works out at 16 A rather than 20 A. Values above assume a 30 °C ambient; a hotter environment requires the correction factors in the same article. These are code values for the cord type, not a TEBAOFLEX performance claim, and the applicable code edition for your jurisdiction governs.

Nominal outside diameter and shipping weight depend on the conductor count and the finished build, so they are confirmed against the production drawing at quotation rather than published as a single figure here. The one published example on this page — an 18 AWG two-conductor build at 0.285 in — is that specific configuration only.

Standards and Compliance

State the required listing, approval, cable marking, standard edition and destination-market documentation in the RFQ so these can be matched to the quoted construction.
