We are in the process of running a new circuit to an electric oven at a lab testing facility. The oven is nameplated at 5800 watts @208 volts (27.9 amps). My first thought is to add 25% for constant duty and make it a 40 amp circuit with a 40/2 circuit breake along with a 50 amp receptacle and plug.
On second thoughts is this overkill? Should one consider running a 30 amp circuit because of the fact that the oven will probably cycle on and off? The run is a short distance so running the 40 amp circuit is not the much more in cost.
