Power Cord gauge, Could it be the problem

I am far from being an electrician
I trade in a M2Tech EVO Clock against a PS Audio AC 12 power cord at HiFi Heaven.
It is a 8 AWG gage cord.
I thought ,  the bigger - the better. I had a good price for the clock , so why not a good power cord.
When l connected my McIntosh power amp in a power conditioner ( APC H15 ) , the power conditioner went out of order :  ´´ one of the inner relays is welded ´´ appears on the screen.
After chatting with the service department ,APC will give me an other one.
I have read on the web that this ´´ inner relays welded ´´ is not rare.
I connected my power amp with that cord in the wall socket and every thing is fine.
Now, I am afraid to reconnect the cable to the new power conditioner when I will receive it.

Could it be because of the cord gage  vs  the conditioner capacity ?
My amp was connected to the ACP before with McIntosh power cord without probleme.

Maybe , a short class  about power cords gage , would be OK 
I have read many many post here without finding an explanation.

Thanks

Thanks  Elizabeth
l will wait to get my new ( or refurbiched ) APC 15 power conditioner, to ask the company’s technician about the my 8 awg cord.
When  ,I contacted them , In the begining, I have never mentionned that.I tought ,they could say it was my fault, and refuse to honor their waranty.
Until I have their answer, my MC 8207 will be connected in the wall socket.
l will write their answer  here.
Thanks again

There is no probleme with APC H15 Power Conditioner.
There is no probleme with a low guage power cord.
The way  l understand it now is that I have made a mistake when l have connected those two togheter. Both devices were ´´ on ´´.
l was just too exited when I received the power cord and wanted to connect them to quickly.
Hight power amp. Plus a low guage cord do the rest.
I have connected the new unit l have received as a replacement.
Turn everything  ´´off ´´ in the first place and then , turn everything ´´ on ´´ and the APC H15 just works fine.
This is ´´experience ´´ that is coming in.
