What does it mean to direct wire a kiln? Is there a power cord?

All L&L Kilns that are over 48 amps are direct wired. That means that there is a power connection block inside the control panel. You will need to have an electrician run a cable or wires in a conduit or flexible liquid tight conduit from your power supply (circuit breaker panel or disconnect switch) into the kiln control panel. Because of all the the possible variations L&L does not provide any of the materials or cables for this.
