Re: Electric duct heater
Depends on the units name plate ratings.
If it says max over current device 20 amps you are all set.
If it says max over current device 15 amps you can change the breaker to 15 amps and be done.
If it says max Fuse size 15 or 20 you will need a fuse to match the size indicated.
The short answer is you must provide the OCPD that the name plate specifies.
