I’m sorry I started a thread that became unpleasant. When I spoke to my electrician he said as long as it is connected to the correct sized breaker an unfused disconnect can be used. I chose to use a fused disconnect and a surge protector just in case. It works fine and was only a few more...
So I finished installing the unit and it came out well. I used 8 awg wire, 30 amp fused disconnect and a 30 amp breaker. I also installed a surge protector. I must say it was very easy to install and the unit works great for AC so far. I’ll see how the heat is in the winter. Using 8 gauge wire...
He said if it's connected to a 30 amp breaker, a fused disconnect is not needed.
And If the breaker was bigger than 30amp, then a 30amp fused disconnect would need to be used.
Is he mistaken? If so, how?
I spoke to an electrician friend of mine and he said the following -
I can connect to the existing 8awg wire and keep going to the disconnect box.
Switch out the breaker to a 30 amp.
He said the disconnect doesn't matter, I can get any size unfused disconnect as long as I have a 30amp...
I'm looking at this wire closer and the text on it says 8 gauge with a 10 gauge ground, sorry for the mistake.
So I can add onto this with 8/2 wire the rest of the way. Might be overkill but it's already half way there.
And the manual says 8 AWG is "preferred"
Last night I looked at what is there and the existing heater has 10/3 wire going to it. If I can use the existing 10/3 wire I would need to add about 25 feet. The total run would be about 45-50 feet.
Right now the breaker is 50A.
I have 10 gauge going to an electric heater halfway to where I would want to mount the disconnect box.
I'm going to decommission the heater so can I just connect to that wire once I disconnect the heater and run it to the disconnect box?
Oh, I see the reply you got from MrCool that said a non-fused disconnect was OK.
What fuse size did you need to get for the disconnect?
I'm glad it's working good! I'm excited to install this.
Ah, I see this can get confusing. I believe you have the same unit that I have but will confirm later.
So you used 12 gauge wire, 25 amp breaker & a non-fused disconnect I see.
Everything seems fine? How is the unit working for you?
Also, which disconnect did you go with?
