customer. Information provided by the manufacturer may constitute such an agreement.


NOTE National US Electrical Code states that:

1) the free length of a field wiring lead is not less than 152 mm long or 100 mm when intended for installation in
an outlet box;

2

2) a lead that is intended to be spliced in the field to a circuit conductor is not smaller than 0,2 mm (24 AWG)
and the insulation, when rubber or thermoplastic, is not less than 0,8 mm thick.
