8.2 Table of internal fuse and external supply ratings.
All furnace models are single phase. Most models have internal fusing as in the Table 8-2 and
Table 8-3 below. Customers should check the rated amps in the tables below and make sure that
their electrical supply is rated accordingly (or at least the next fuse size up from the rated amps
table). Customers should also fit external fusing if their particular model of furnace does not have
internal fuses. The function of the customer's (external) fuse is to protect the customer's wiring.
All electrical connections other than where it is just a simple plug into an existing correctly rated
electrical supply must be carried out by an electrically competent person with the correct
certification to meet local legislation.
