UL 83 Standard THHN 350mcm electrical Wire
APPLICATIONS
THHN or THWN-2 conductors are primarily used in conduit and cable trays for services, feeders, and branch circuits in commercial or industrial applications as specified in the National Electrical Code. Voltage for all applications is 600 volts.
When used as type THHN, conductor is suitable for use in dry locations at temperatures not to exceed 90°C.
When used as type THWN, conductor is suitable for use at temperatures not to exceed 90°C, dry locations or 75°C
wet locations or not to exceed 75°C when exposed to oil or coolant.
When used as type THWN-2, conductor is suitable for use in wet and dry locations at temperatures not to exceed 90°C or not to exceed 75°C when exposed to oil or coolant. Conductor temperatures not to exceed 105°C in dry locations when rated AWM and used as appliance wiring material. Voltage rating for all applications is 600 volts.

24v DC Worm Gear Motor is the most common used worm gear motor. Dc Worm Gear Motor has a low efficiency, so while working, it is necessary to save energy as much as possible.
DC Worm Gear Motor including a dc motor with a worm gearbox. A worm gearbox means the output shaft is vertical with the dc motor shaft. Connecting the gears with the motor, there is a worm gear. DC Worm Gear Motor has very low efficiency, normally for the first stage, the efficiency will loss at least half. However, dc worm gear motor is widely applied on some products need with self-lock function. Like the automatic range hood in the kitchen, or the roller blind motor.
The dc worm gear motor has the following characteristics:
1. Achieve great speed reduction through high gear ratio. Normally reduce the speed as low as 3-5 rpm.
2. Achieve vertical transform by the worm gear
3. With self-lock function to prevent the back-driving.
