Trying to keep this short.

I have a VE-200 and a VE-300x2.

I have 2 racks. When I use the racks with their
own thermostats plugged into different outlets
they work fine. When I try to connect both racks
to the VE-300x2 they don't heat up correctly.

Also today I tried to move my leopard gecko setup
and plugged it into the surge protector along with
one of my racks which caused both the rack and
gecko setup to not heat up correctly.

It seems like the only way any of them will work
correctly is if they are plugged into their own
outlets. Also all 3 outlets are piggy backed off
one another. I rent the house.

I'm lost, I am clueless when it comes to stuff like
this and I have another rack otw. Any help would
be so appreciated.
