480 Volts

Standard DaVinci and JD2900 kilns have three elements per section. Elements are wired in a Star (Wye) Configuration to get 277 volts at the elements. This means the voltage potential in the kiln is much safer than it would be if the elements were running at 480 volts.
On Quad versions, we use two 240-volt elements in series.
The power supply does not require a neutral (it is a "floating neutral).
Watts are the same as 240-volt kilns. Amperage goes down.
An optional NEMA 1 control panel is a special heavy-duty industrial control panel. These panels are floor-standing on an included stand. They typically sit on the right side of the kiln. Note that you need the NEMA1 panel to get the MET-us listing. The price of the NEMA 1 panel is added to the price of the basic 480-volt option.
Each kiln section is separately branch fused.
A lighted “On/Off” switch is included.
Kiln sections are “hard-wired” (meaning that there are no plugs and receptacles) from the sections to the control panel with a flexible “SO” cord (typically 72” long each).
These 480 Volt kilns are c-MET-us listed to UL499 standards if the NEMA 1 panel is ordered.
