When we hear a camper say, “Your electric breaker is bad,
because all I’m running is my water heater and air conditioner and it keeps
tripping!” we know we have to share more info with them!
Brace yourselves, because here comes the truth you may not
want to hear! Are you ready? Just because the RV manufacturer put all of
those electric appliances in your RV does not mean you can run it all at the
same time! There, we said it. Yes, we know, it hurts a little, but it is
the truth. And you need to understand
what exactly that means for you, as an RVer.
If your new travel trailer is wired for 30 amps (110 volts),
your RV can sit on a 30 amp campsite.
That’s great, you think, because the 50/30 amp sites cost more at the
campground! So, it saves me money! True story!
It certainly does. And the RV dealer
sales person may have even told you, “This baby has a propane/electric water
heater, so you can heat your water on electric and save even more money, by
having to purchase less propane.”
However, that is not necessarily true.
A 30 amp campsite only provides 30 amps of electricity or
slightly less, depending upon the safety margin and age and condition of the
breaker itself, it could provide slightly less – like 26-27 amps.
So, like the case of the camper above says, “I was only
running my water heater and air conditioner.”
That is never true. More
experienced RVers know that you are running your air conditioner (15-17 amps),
water heater (12.5 amps), refrigerator (5.7 amps), and electric converter (2-3
amps)! You were trying to pull almost
35.2 amps on a 30 amp breaker. (Light
bulb comes on!) The new RV thinks, “Oh wow, now I see the issue! So, I guess I can’t do that?” Yes, that’s right. You have to shut something off. You can shut the refrigerator over to gas,
and that might bring you below the threshold for the breaker to not kick, but
that is, until you turn on a light, the TV, or the wife tries to make coffee,
dry her hair, or attempts to thaw the chicken in the microwave, in which case,
you’re outside resetting the breaker again!
In addition, if your RV comes with an outside kitchen with a
refrigerator, it too is running and eating up another 5.7 amps or so of
power. And so on it goes! That 12.5 amps the water heater is using is
the easiest way to drop that amperage draw back down below a safe area that won’t
trip your breaker. It gives you the room
and flexibility to dry your hair, run the microwave, or have lights on.
This has been a recurring theme this summer as more people
are buying these travel trailers that are wired for 30 amps – and trying to
operate a 42-45 amps of electrical appliances draw off a 30 amp breaker because
they are running their propane/electric water heaters on electric. And apparently, some RV dealers are telling
people to do that – as a sales pitch that it’ll save them money.
Okay, so how about if I move to a 50/30 amp campsite. Can I do that? Yes, you can do that, if one is available,
but that won’t help the situation. Your
RV is only wired to use 30 amps! You
cannot plug into a 50 amp hookup with an adaptor and draw more than your 30
amps, anyway! The only way to prevent
breakers from tripping is to manage you amperage usage.
Below, we’ve attached an info sheet that will show you the
approximate use of different appliances.
You are free to go through your RV and calculate your own
appliances! The sheet will show you
how! Hopefully, it’ll be of some use to
you in calculating your approximate electrical usage, and save you some time
and aggravation! So if you’d like a hard
copy to keep, please email us, and we’ll be glad to email you a copy. We sincerely hope it helps you!
Before You Blow Your Breaker!
Take a minute and see how many amps you could be using in your RVs 30 or
50 amp electrical system. It is surprising how fast the amps add up which
causes your breaker or the RV park's breaker to "trip". Knowing the
amps of all the electrical appliances in your RV can help you manage electrical
use and prevent the inconvenience of "My electricity went
out!".
This list is the typical appliance used and the average amps required to
operate them:
|
Air
Conditioner
|
15-17 amps
|
|
Refrigerator
|
5.7 amps
|
|
Electric
Water Heater
|
12.5 amps
|
|
Microwave
Oven
|
12.8 amps
|
|
Electric
Coffee Pot
|
9 amps
|
|
Toaster
|
10 amps
|
|
Hair Dryer
|
10 amps
|
|

|
|
1,100 Watt
Heater
|

In the morning - if you start your air conditioner and
the hot water heater is on, then you start your coffee pot, make some toast,
watch some TV - you are pulling 50 amps when all appliances are operating at
maximum. If you also cook something in the microwave at the same time - LOOK
OUT! Most RVs have a switch so you can run only the microwave or the water
heater at one time - HOWEVER, NOT ALL RVS HAVE THIS FEATURE.
Most electrical products show how many watts or amps
it takes to operate the appliance printed on the product itself or on the
instructions. If it shows the watts - divide the watts by 120 (volts) and that
gives you the amps. To get the watts - multiply the amps by 120 (volts).
It is worth your time to take an inventory on the
"amps" each of your electrical appliances uses, then you can manage
your total usage at one time and this greatly reduces the "My
electricity went out!" anxiety.
