I plan to connect the generator output and the power company mains using this manual ts. where do i connect the 'earth' wire?

The grounds are common, so the grounds can be connected together. The neutral needs to be switched through the switch.

can this take 16 mm cable in the terminals ?

16mm or 16 gauge? It can take up to 14 gauge MAX. I tried 12 gauge stranded and it wouldn't fit

How would i wire this to act as a spdt switch on 12v dc? i wish to switch between two power sources. any advice is appreciated.

You would have to connect a jumper on the output side. (eg. sw to pos 1 will connect pole 1 and 3. sw to pos 2 will connect pole 2 and 4. pwr source 1 to pole 1 and pwr source 2 to pole 2. add jumper btwn pole 3 and 4 and use pole 4 as an output.) NOTE!! Check pole switching this is just an example!!! also be aware of the amperage this is an AC switch box.

I need to switch between two ac sources, do i use 1/3/5/7 as the output? i follow that 2/6 for pos1 and 4/8 for pos2 , but what output terminals?

Connect the load's hot wire to positions 1&3. Connect the load's neutral wire to positions 5&7. Connect AC Source #1's hot wire to 2. Connect AC Source #1's neutral wire to 6. Connect AC Source #2's hot wire to 4. Connect AC Source #2's neutral wire to 8.
