MCA = Minimum Circuit Ampacity
MOP = Maximum Over-current protection
*Recommended Field Wire Size per NEC Table 310.16
Not more than three (3) current carrying conductors in raceway
Based on ambient temperature of 30ºC (86ºF). Other ambient temperatures see NEC or CEC for correction factors.
Use Copper conductors only.
Recommended use only Class B or C type wire (see Table B).
Check with latest version of NEC and local codes.
UL-834, Section 14.2
Assuming 60ºC (140ºF) wire will be used for connections to boiler rated at 80 amperes or less, and 75ºC (167ºF) wire will
be used with boiler rated at more than 80 amperes.
