The National Electrical Code (NEC) was written to provide a set of rules and regulations to keep the use of electricity in your home safe. Here are the top bathrooms codes you need to live by to remain safe and keep your electrical devices working properly.
You may wonder why the electrical inspector seems to be so tough on you when he explains all of the requirements in your bathroom. You may ask why you need things like GFCI's, timers for tubs mounted at a distance from the tub, and exhaust fans.
He may tell you that you need a separate circuit for your outlet, but after you consider everything that will probably be plugged into it, you soon see that the inspector is there to help you to have an effective and safe electrical plan.
I have talked with many people throughout my community that seem to think that the inspector i out to get them. He or she is just picking on me. They seem to consider themselves the only one that has to do this. As an electrician, I have to convince them that they are not alone, everyone must follow the guidelines of the electrical code for their safety.As is with many things in life, we get caught up in the way it used to be just isn't the way it is gonna be now. Some just don't understand why they need to change something in their home that has worked just fine for all these years. They have never been hurt up to now, so why the change?Let's take a look at some of the bathroom requirements and you can see if your home stacks up to the codes.
I'm often asked what the NEC requires in different parts of the home. This section will deal with bathrooms and its safety.
Each bathroom should have a circuit for lighting and an exhaust fan. This may include a blower-heater-light combination.
There should also be a 20-amp circuit, separate from the lighting circuit, to provide power for an outlet to feed things like curling irons, razors, hair dryers, and even portable milk house heaters.
Connected to the outlet circuit, you should install a ground fault circuit interrupter (GFCI) to protect the user. A GFCI trips and disconnects the circuit power if it senses a difference in potential on the circuit, like a short circuit or a path to ground, which could be right through your body. This device is very important and can save your life!
Since bathrooms are wet, switches should be grounded as well to give any stray voltage a direct path to ground, instead of through you. You'd hate to get out of the shower, soaking wet, and get shocked by touching a switch.
Place exhaust fans or heater-fan-light combinations far enough from the bathtub, shower, or hot tub so that no one can stand in water and touch it. I'd like to see the fan located somewhere over the toilet area.
Just remember, these are bare minimum requirement and you can add more circuits as you see fit to accommodate the load of the appliance you plan to plug in or add to your bathroom. For all I know, you may have three girls needing to use a hair dryer at the same time.
In that case, I'd add a circuit and GFCI outlet for each hair dryer.
Here's a great tip to keep in mind...for each motorized appliance or device, add a separate circuit to feed it. That way, you'll have ample circuitry to handle every situation in that area of the home. You'll thank me later when you really need it, so plan ahead. I am so glad I added extra outlets around my home and so will you!
