Just try to change my water heater switch but some queries.
Any kind soul out there pls share some tips on doubts I have :
Q1. L1 / L2 = should be connected to White Color cable ?
Q2. N1/N2 = should be connected to Black Color cable ?
Q3. Earth - should be connected to yellow/green stripe cable ? But from the wall outlet it has two such cable, should connect both into this slot?
Q4. See pictures. Notice there are two tiny Black cable below L1/N1. Not sure where it should be both connected to?
