Pedalboard power conundrum... electrical advice needed!

Norwegian_Blue

I guess this fits the effects area best... please tag anyone you think might have the knowledge! 

I'm hoping to have a tidy up of my board shortly, and one of the biggest pains I have is this bulky IEC splitter which allows me to power my Gigrig Generator and Noble DI from one IEC input on the board. 

I've definitely seen examples of people running two cables directly from the IEC input, and had it mentioned to me as an option but cannot seem to find proof that A. it's safe and 2. It will work well. I can't see it being any different from using a splitter but I'm really not versed in this stuff. if it's possible and anyone wants to make me a tidy twin cable input with a boot I'd be delighted!
