Both type thwn-2 and type <u>THHN </u>conductors have an insulation temperature rating of 90 degrees celsius and generally meet the temperature requirement for connecting luminaires.
<h3>What is the difference between THHN and XHHW conductors?</h3>
The wire's jacket is the primary distinction between THHN/THWN/THWN-2 and XHHW/XHHW-2 and. The THHN family's jacket is thinner, thus even while more THHN can fit through a variety of barriers, it doesn't provide as much protection as the XHHW jacket. Additionally, the coating on the jacket of the XHHW is more resistant to chemicals, ozone, and abrasions, whereas the thinner coating on the THHN, when exposed to harsh chemicals or the environment, can cause current leakage and eventually degrade, releasing hazardous smoke when burnt.
As always, performance against budget must be taken into consideration when deciding whether to use THHN or XHHW. THHN wire is ideal for their requirements. However, XHHW has the extra characteristics that offer greater effectiveness and longer durability.

The correct answer is B.
Gas rationing occurred during WWII in order to help control gasoline usage which was in short supply.
The U.S. Office of Price Administration issued a variety of stickers to identify users and control the amount of petrol used.

America and Japan were not at war with each other
Explanation:
The attack on Pearl Harbor considered a surprise because United States and Japan were not at war with each other. U.S was a neutral country at the time and an attack on Pearl Harbor was ruled out because it was believed the Japanese lacked the capacity to mount such an operation; United States at that time was likewise hoping to avoid being pulled into World War II at any cost. The attack was carried out because of the transfered of US Pacific Fleet from California to Pearl Harbor in 1939 which was considered a threat because of the Japanese interest in the resources of Southeast Asia.
