Lafayette electricians needed, Transfer switch install
Posted on 7/6/21 at 7:37 am
Posted on 7/6/21 at 7:37 am
I want to install a transfer switch, so I can run a few circuits with my portable generator. Usually, I do most of my own home improvement, but this one has me a little nervous. Also, I do have a solar system on my house. I’m leaning toward hiring an electrician for this one.
Anybody know someone with fair pricing who could/would handle this job?
2nd question: I have a 6500/5500 generator. Could this potentially run the a/c?

Call Sorrel Electrical. Great group and pricing.

I'm not an expert, but I'm pretty sure the 30A on that generator wouldn't be able to handle it.
You'll need to get one with a 50A plug and an EasyStart to have a chance of running the central A/C on a portable.

Before you commit to the transfer switch, you can also look at getting an interlock kit installed instead. They are cheaper and gives you access to the whole panel instead of the ones dedicated to the transfer switch (just be careful to not overload).

A 6500 generator will not safely run your central air. Don’t even attempt it, you’ll frick up either the ac or generator - or both.
Also, don’t pay all that money for a transfer switch and get an interlock kit installed on your panel instead. It’s much cheaper and you can choose which circuits to use instead of having only a set few as options. I had an interlock kit installed a year and a half ago and bought a 10,000/8,000 generator and I still don’t even attempt to run my central air. I have a couple window units that I install whenever I have an extended power outage and can run just about everything else except the central air. Just not all at the same time. Two window units, all lights, and fridge/freezer along with internet at the same time. Need to wash clothes? Turn off everything else and run the washer. Then turn the dryer circuit on and run the dryer. After that I can use everything else again. Basically it’s a whole home generator set up except the central air for 1/10 of the price.
The generator and cost for an electrician to install the kit (and the kit itself) was $1,600.

This is simply not true.
One other poster mentioned a Micro Air soft starter and that’s probably one of the few ways that it’s feasible.
The size of your unit will be one of the biggest determinants in whether it’s possible. Looking at the Rheem product catalog, their RA16 1.5 ton unit draws 9 amps at full load (2160W). They list 47.5 LRA but that amount can substantially be dropped with a soft starter. Also keep in mind that both your air handler fan and compressor fan will draw a bit of current (though considerably less than your compressor).
Having said all this, if you plan to do it, I would buy the soft starter first to measure the starting current on your unit or call the company and consult them. Then verify that your generator can handle that amount of inrush. They may give you an idea of just how much you can drop the starting amps to see if it’s possible with your specific unit.
Keep in mind that running central air may be the only load your small generator can handle. There will not likely be room for much else unless you upgrade to a larger size.

You just spoke German to me
I’ll just stick to a couple window units if I lose power lol

Thanks everyone. I googled the interlock kit and that seems to be the way to go. We really only want to run the fridge, and bedroom light, and fans. I liken the options of switching things on and off. I’m not worried about washing clothes or cooking. We can wait on clothes and cook outside.
I figured the A/C was just a dream. So, next steps:
1) Find and electrician, I’ll start with the suggestions.
2) Purchase the interlock kit. Should I talk to the electrician first?

I’ll dumb down what I’m saying for you.
Most generators can power central air when they are running normally. This would be considered “full load amps” (to keep it basic).
The problem most generators have is starting up central air units. They simply do not have enough juice to get them moving initially. Imagine trying to push a very heavy box across the floor - you need that initial jolt of energy and inertia to get it in motion. Once it’s in motion, it becomes less difficult to keep in motion.
Ever seen the lights in your house dim when your AC kicks on? That’s typically from the initial jolt of “starting current” (also sometimes called locked-rotor amps, LRA). Considerably more electrical energy is needed to get motors in motion. This jolt doesn’t last long but can be 4-8 times the full load amps (depending on the motor).
What a soft starter does is power a motor slowly rather than hitting it with 100% of available power at startup - think of increasing radio volume slowly by turning a knob. The unit mentioned earlier can reduce starting current substantially in this manner.
So depending on sizing, a portable generator can power central air with a soft starter.

You probably don’t have to but I’m admittedly an idiot with electricity so I just had my electrician get one and install it for me. Just told him I wanted one and he took care of the rest.

Thanks for the explanation. When I get an electrician out here, I’ll bring it up.
Again, having the ax would be awesome, but really isn’t necessary. We were comfortable last hurricane with just the fans. If needed, our in-laws have a whole home generator.

Interlock is the way to go. I have it interlocking the main breaker and the dedicated 30A breaker that is fed from the 30A generator plug on outside of house. I have a 9375/7500 portable and it will start my 3 ton AC but I would only do that when no other options. I have 2 window units if I need AC. Seeing that my furnace, dryer, and range are natural gas I can run the rest of my house no problem.

With a portable generator an interlock should be the only thing he does, transfer switch is way overkill
