What makes ul1569 and ul1007 different from one another?
Numerous UL 1007 cables also satisfy CSA type TR-64 and UL 1569 requirements. The temperature ratings of the three standards differ from one another the most. With a maximum temperature of 105°C, UL 1569 has the widest temperature range of the three. Additionally, these lead wires are frequently offered in several AWG sizes.
Are V and U neutral or alive?
Not at all. They "switch" anything that is hooked to them since they are merely two sides of a switch; they NEVER act as a neutral. Since a switch has two sides, U and V, EITHER can be the "load". Be it a pump or a relay, U and V will simply "switch" whatever you connect to them.
