WIRE SIZE
When selecting the type and size of wire used to install the TORREXX series
electric vaporizers, please consider the following environmental information:
■ Maximum enclosure surface temperature: 65ºC (150 ºF).
■ Maximum enclosure ambient temperature: 80ºC (176 ºF).
■ Maximum temperature at relay terminals: 80ºC (176 ºF).
■ Current draw of vaporizer: Indicated on vaporizer rating plate and on the
data sheet.
■ Power distribution block terminal lug wire size range: #2 - 14.
For Zone 1 installations the phase conductor wire must be of the same size as
the factory provided #8 AWG (3.26 mm diameter or 8.3 mm
2
cross sectional
area) ground wire. Refer to Table 3 for wire run limitations based on vaporizer
current draw.
For Zone 1 installations the size of the grounding cable shall be in accordance
with the table below. The minimum permitted size of the equipotential bonding
connector is 4 mm
2
.
When installing the wire, it is important to have a good connection at the terminal
lugs. Loose terminals may cause an excessive temperature rise at the terminal
lugs, which can lead, to premature solid-state relay failure, and/or overheating
and possible destruction of the transformer. For this reason, it is strongly
recommended that the wire terminations be checked and re-tightened
periodically to prevent excessive overheating at the terminals due to loose
connections. Always ensure term inals a t the heater pins are tight. If not,
torque to 10 in- lbs (1.13 Nm).
