Raceways and Wireways for Channel Letters
Raceways are (usually) 8 tall by 8
deep boxes running the length of a sign, behind the
channel letters.
This box contains all of the
electrical components powering the sign, so that the
raceway can be fastened to the outside of the building,
and only one power hole needs to be drilled through the
wall. (If the letters are mounted directly to the
wall each letter requires two (2) 1 diameter holes be
drilled through the wall, and all of the electrical
components install behind the wall.)
The best raceways are manufactured of
aluminum, with a structural steel inner frame which is
primed, before the aluminum skins are installed, to keep
it from rusting.
Raceways are usually painted to
closely match the wall color.
The best raceways incorporate glass
neon electrode connectors, making the sign much more
reliable.
A raceway should include a disconnect
switch to help you comply with your city's electrical
code.
Wireways are 2 deep by 12 tall
(usually) aluminum boxes which contain all of the wiring
except the transformers (which mount behind the wall.)
Wireways are usually incorporated behind backplates and
required by the landlord. They are not deep enough
to incorporate glass neon electrode housings.
The use of raceways is usually
dictated by a landlord also, or by a lack of access behind
the wall
where a sign is to be installed.
Both are easier to move at a later
date.
Notice the raceways between the
letters and the wall in the installation on the right.
