having an issue with a t104 timer ... need help !!

I got a 12awg wire running from the 240 stove plug into a t104 timer then into 2 x 4outlet boxes and 1 x 2outlet box.
Every thing is supposed to be wired right , the neutral wire is plugged on the A , hot black line
on port 1 , hot red line plugged on port 3 , ground on ground . Port 2 and 4 going to load with the ground and neutral wire.
Once all that is plugged , it wont fire up the 1000watters but when i plug a 600 watter it fires up .. ?? any one know what
can be causing this problem ??
Maybe the outlets are not plugged right?

If your ballasts are set for 220 vac then your plugs are mis-wired.
Those plugs are wired for 110.

To wire for 220 you would need to feed red to silver terminal and drop white wire completely.
Do Not drop the ground though.

No help from me, but I'll give you a rep for using the AK-47 of timers.

Have one Intermatic that has been in service for over 40 years and still going.

But, I get my brother the electrician to wire them for me, T-101's.
