Re: Re: What's the REAL story with LD11's and heat?

["Simon Coates" <ecolume@xxxxxxx>]

I'm installing a similar setup to you, but using Hager 54 way boards.  I've
found them to be the best/most cost effective way to install lots of AD10s
and LD11s.  I'm using 1/2 blanks between the LD11s and adding ventillation
holes to minimise heat build-up.
