Electrical Connections
Connection by a qualified electrician is recommended.
The furnaces covered by this manual require a single-phase A.C. supply with earth (ground). The
supply may be Live to Neutral non-reversible, Live to Neutral with reversible plug, or Live to
Live.
Check the furnace rating label before connection. The supply voltage should agree with the
voltage on the label, and the supply capacity should be sufficient for the amperage on the label.
The supply should be fused at the next size equal to or higher than the amperage on the label. A
table of the most common fuse ratings is also given in section 8.1 of this manual. Where a supply
cable is present there are internal supply fuses; customer fusing is preferred but not essential.
Furnace with supply cable: either wire directly to an isolator or fit with a line plug.
Furnace without supply cable: a permanent connection to a fused and isolated supply should be
made to the internal terminals after temporary removal of the furnace back panel.
Connection by line plug: the plug should be within reach of the operator, and should be quickly
removable. Connection to isolating switch: this should operate on both conductors (single phase)
or on all live conductors (three phase), and should be within reach of the operator.
Single phase: connect the supply as follows:
Cable colour
Brown
Blue
Green/Yellow
The supply MUST incorporate an earth (ground).
Technical Note (1400°C Models)
The 1400°C models have an electronically controlled power limit. Do not attempt to calculate the
Amps from the Wattage. High break capacity fuses should be used. Avoid fast-blow fuses and
magnetic trip circuit breakers - consult Carbolite if in doubt.
