The outlet/receptacle in my garage for my sprinkler timer is a single,
20-amp outlet. I went to replace it with a dual 20-amp outlet so I could plug more than one thing at a time in. In doing so, I discovered that this circuit is controlled by a 15-amp breaker (this circuit also contains another 15-amp GFI outlet in my garage).It's a new home, still under warranty. I reported this to the builder. Two concerns:
- Maybe it is supposed to be a 20-amp circuit and they tried to make it look like one with the 20-amp outlet. All other add on outlets to the house are 20-amp. The outlet for the sprinkler timer is an add on since the front yard landscaping was an option. I don't think they'll ever tell me for sure if that should have been a 20-amp circuit and they forgot to put it in, so they piggy backed off of the exisiting
- Is it legal for them to put a 20-amp outlet on a 15-amp circuit? I asked this question. The builder said "for the sprinkler timer, they are allowed to use a single 20-amp outlet/receptable even though it is a 15-amp circuit." What??? That doesn't make any sense.
Am I being BS'ed? I cannot get access to the NEC code book to research this myself. My county uses the 2002 NEC. Thanks in advance for any input.
