Default Johnson control

Will a Johnson control handle a 2000 watt heating element with using a relay?

What model? If it's rate 10-15 amps.... I would not do it.

amps X volts(120) = watts

so....

10(amps) x 120volts = 1200 watts (for example)

I have the A419... a quick Google search and it looks like 1500 watts is the max.

Sorry,, M1k3 , it's the 419 unit. I've been running a 1500 watt unit straight through it without any problems. I was thinking that I needed a relay to run the 2000 watt unit and the johnson.

Just found the specs on the A419.. Only rated at 16amps, So the 2000 watt will be pushing it at 16.66 amps..
