[RE-wrenches] wire gauge reducers

[William Miller]

Colleagues:

There is no shame in referring to these devices as reducers.  As long as 
the smallest conductor size meets ampacity and voltage drop ratings, the 
use of larger copper is something to be proud of.  It indicates an 
awareness of efficiency through design.

We don't favor splices that are not secured to a mounting surface.  We want 
to be able to access a conductor for testing and labelling and we want to 
know where it is in a given enclosure.  Therefore we use power distribution 
blocks such as those manufactured by Greaves, Ilsco and Square D.  Here is 
a link to Illsco:  http://tinyurl.com/l6msc6
