A very amusing building code item

The applicable building code here in Solomons (and perhaps all of Maryland, for all I know) requires that if you have a non-dwelling structure, such as a garage, wired for electricity, any person-entry door that's not big enough for vehicles has gotta have an outside light beside the door, controlled by a switch inside the building. I haven't the slightest idea why.

My old garage (now ripped down to make way for the new one) had such a light, put in when I had the place wired about 25 years ago. The light was never turned on, except maybe once every few years to see if it still worked.

It's a non-dwelling structure. When you're approaching the door from the outside, the light is off, and you can't reach the switch until you're into the building, at which point you don't need the outside light so you're not gonna bother to turn it on.

When you leave the building, you're gonna make sure all lights are turned off as you leave. So the outside light will never been used.

So now that my new garage is being built, I've saved the old outside light so the electrician can re-use it. Hey, it's brand new! Never been used! And never will be used!

I wonder which state legislators had their heads stuck up places I don't wanna know about when they enacted that law.

Anyhow, I've asked the builder of my new garage to put in a motion-detector light on the front of the building, where it will actually be useful when I need it, even though the building code has no such requirement.

My shop is about 25' from my back door and has a light beside the door, but it is wired so that I can turn it on and off from the inside of my house as well as inside the shop.

just like a bunch of rich republican types to be bragging about how they can afford a light bulb.

National Electrical Code. Look it up. You're welcome.

Ooh! National! Well, as long as they let me have everything I want, I'll just take the useless extra stuff and quit complaining.

I've gone through the garage marking where I want stuff, and I labeled the outside back door light "Useless Building Code Light". I bet the electrician will just love my attitude for that.

Is your garage attached to the house? My shop is not and without that light I wouldn't be able to find the door at night.

NEC article 210-70(a)(2) states:

"At least one wall switch controlled lighting outlet shall be installed in hallways, stairways, attached garages, and detached garages with electric power; and to provide illumination on the exterior side of outdoor entrances or exits with grade level access."

No. It's about 50 feet from the house. It's well-illuminated by the back yard light on the house.

We always include a fudge factor for homeowner attitude in our quotes... :lmao:
We do the same.
it can range anywhere from 5 to 10% depending on the fudge production abilities of the homeowners fudge factory.

in rare cases where the fudge is flowing at a rate that exceeds our ability or desire to wallow through it, we will do a 25% fudge factor just to avoid taking in the additional calories to do the job.

But apparently the code permits putting 22 amps of light fixtures onto one 15 amp breaker. I've gotta pay extra to get the electrician to divvy the load onto two breakers.

:nono: Article 210-20(a) Where a branch circuit supplies continuous loads or any combination of continous & non-continous loads, the rating of the overcurrent device shall not be less than the non-continous load plus 125% of the continous load.

In laymans terms you can only have up to 16 continuous amps on a 20 amp circuit.

Continous is defined as 3 hours or more.

The code allows for diversity. Diversity is the logic that not all loads will be on at the same time.
