You should be safe.

It is always OK to put a lower load on a higher rated receptacle.
(At the proper voltage that is. Don't mix 230V and 115V).

Just think of it this way: If it wasn't OK nobody could plug a phone charger (about 2 Amp max) in a standard wall-outlet (10 Amps or more).

And for the record: I am a qualified electrician. 
Even though it's been over 20 years since I worked in that field, the laws of electrical physics haven't changed.

I still recommend you have a electrician sort out the converter plug or cable. The cheap stuff you can buy online is often of shoddy quality. If you buy it yourself get it from a reputable source. 
An UPS for, presumably, important equipment is not the place to skimp on quality.

Why not just plug into a NEMA 5-15 or 5-20 receptacle? You don't need to use the L5-30 circuit.

But yes, you can do this. It's possible to just <a href="http://www.quail.com/P-WS-114/Nema-520r-To-L530p-Adapter-Black.aspx" rel="nofollow noreferrer">buy an L5-30P-NEMA 5-15R pigtail adapter</a> online or manufacture your own. However, I'm assuming you have plentiful 5-15 receptacles available to you. Is there a reason you can't use one of those instead?

If the voltage is the same (120v in your case) and the Amp rating is less (15 &lt; 30 in your case), then Yes.

<blockquote>

Yep. An eletrical supply house would have this. You should be able to find one on the Googles too.

blocks|key|4834330|text|就像MadHatter提到的，我们不是这里的电工。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4834331|但我对此的看法是，Amps就像一个最大的负载，你可以用它来引导电路。在这种情况下，更重要的是(据我的非电工所知)，您的新UPS可以处理120伏电压。很有可能是真的。|4834332|我不认为你会为此找到适配器，我相信扭转型插头的关键是确保物理连接的安全。拥有一个适配器会很难达到这个目的。|4834333|我会找个电工过来换一下插座。|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|J|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|K|8|@]|9|@]|A|$]]|$1|F|3|G|5|6|7|L|8|@]|9|@]|A|$]]]|H|$]]

Like MadHatter mentioined, we are not electricians here.

But my take on that is that the Amps are a like a maximum load you can bruden the circuit with. What's more important in this case (with my non-electrician knowledge) is that your new UPS can deal with 120 volts. It's most likely the case quite honestly.

I don't think you will find adapters for this, I believe the point of twist type plugs is to secure the connection physically. Having an adapter would pretty much defeat the purpose.

I would get an electrician over just to change the receptacle.

<blockquote>

</blockquote>

It LIKELY is safe, but the UPS fuse LIKELY is OUTPUT - and the UPS can suck a lot more power because it msut deliver it's maximum load AND LOAD AT THE SAME TIME. The documentation (of the UPS) will have requirements for the input circuit.

blocks|key|5878593|text|如果您要使用适配器，请将断路器改为15A断路器。这样就避免了所有的风险。那是5美元的一部分。如果你不能安装10+AWG电线在断路器，它与14+AWG电线用一个合适的螺母。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|5878594|专用电路(具有单一出口的电路)应该有一个断路器，它不仅保护电线，而且保护与之相连的电器。由于您的“设备”是您的UPS额定为15A，它应该有一个15A断路器保护它(或至少，一个保险丝内置在适配器)。|5878595|这同样适用于内置电器。例如，40A或50A电路上的30A烹饪顶部通常需要30A断路器。这种情况通常发生在炉灶容器经过改造或翻新后，被重新用于烹饪顶部。有时，制造商会声明允许连接到40A或50A电路，但在15A设备的情况下，几乎总是说该设备应该连接到具有15A过流保护的15A电路。|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|G|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|H|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|I|8|@]|9|@]|A|$]]]|F|$]]

If you're going for an adapter, change the breaker for a 15A breaker. All risks are then avoided. That's a $5 part. If you can't fit the 10 AWG wire in the breaker, splice it with a 14 AWG wire using a suitable wire nut.
Dedicated circuits (circuits with a single outlet) are supposed to have a circuit breaker that protects not only the wire, but also the appliance connected to it. Since your &quot;appliance&quot; is your UPS rated at 15A, it should have a 15A breaker protecting it (or at the very least, a fuse built into the adapter).
The same applies to built-in appliances. For example, a 30A cooking top on a 40A or 50A circuit will usually require a 30A breaker. This happens commonly when a stove receptacle has been repurposed for a cooking top, after a remodel or renovation. Sometimes, the manufacturer will state that connection to a 40A or 50A circuit is allowed, but in the case of 15A devices, it will almost always say that the device should be connected to a 15A circuit with a 15A over-current protection.

I know that typically electronics draw only as much current as they need. Is this the case with UPSs? I have a 120 volt, 30 amp circuit, and am replacing the UPS plugged into that circuit with a lower wattage UPS. This UPS has a 15 amp plug. Is it safe to use an adapter to do this?

Also, the current plug is NEMA L5-30, whereas the newer UPS is 5-15. If this is safe, are there adapters that are L5-30P to 5-15R?

Can I plug a 15A UPS into a 30A receptacle?

我知道典型的电子产品只会吸引尽可能多的电流。UPS的情况就是这样吗？我有一个120伏特，30安培的电路，并且正在用一个更低瓦特的UPS取代插入那个电路的UPS。这个UPS有一个15安培的插头。使用适配器进行此操作安全吗？此外，目前的插头是NEMA L5-30，而较新的UPS是5-15.如果这是安全的，有适配器是L5-30P到5-15R吗？
