This is the designation for a type of flexible cord ("junior hard service cord") for electrical uses up to 300 volts, having thermoplastic insulation of the conductors and a thermoplastic outer covering. The "W" designates compliance with requirements for outdoor use (water and weather resistant), suitable for use in wet locations. There may also be markings that indicate resistance to sunlight (UV) deterioration.
Approved cords should have durable markings every 24 inches showing the type, size of conductors and number of conductors.
The permitted amps through an SJTW depends upon whether it has 2 current-carrying conductors or three or more, and the size of the conductors. An 18AWG/2 is 10A, and 14AWG/3 is 15A, for example (at ambient T of 86F, 30C).

What is the VA rating for common appliances?
For all intents and purposed the VA rating is the same as the wattage rating of appliances. VA is an electrical classification for Volt Amps. The formula for watts is, Watts = Amps x Volts.
What is the voltage rating for ASTM F2413-11 safety shoes?
The ASTM F2413-11 standard includes specifications for protective footwear, including various electrical hazard ratings. Safety shoes that meet this standard may be rated for electrical hazards, typically classified as EH (Electrical Hazard) footwear. This means they are designed to provide a certain level of protection against incidental contact with live electrical circuits, but they do not have a specific voltage rating. Instead, they are tested to ensure they can withstand a minimum voltage level, generally around 18,000 volts for a short duration.
How do you calculate the total electrical wire quantity of a building?
It is done through a specific formula that is outlined in the electrical code book. Specifically taking the highest loads at 100% and pro rating other connected loads at less than 100% to determine the connected load of the building.
