To calculate the amount of cable needed, multiply roof edge
length
to be heat traced by the spacing factor.
The spacing factor (feet of cable required per foot of roof
edge) is
determined by the roof overhang, heating width (A) and heating height (B):

Add the total gutter length and the total
downspout length
to the figure calculated above.
|
Also add enough cable to
provide a drip loop prior to going into the box,
typically 6" to 36", to get the total length of cable required.
Determine how many circuits are required. Divide the total length of cable
by
the maximum circuit length.
Round that number up (for example, 2.1 to 3)to get
the
total number of circuits.
