Separate lighting and receptacle circs?

With using CAFCI breakers, has it become common practice and advised now to keep lighting circuits separate from receptacle circuits in homes ? Thanks

I have to admit to, I've been out of the loop, afci and gfci, when did this cafci come about? what code cycle is it required? honestly first I heard or read about them. Maybe I should frequent here more

AFCIs have been in the NEC since 1996. CAFCI are for where you need AFCI and GFCI, such as kitchen. And if you replace a receptacle it has to be AFCI and or GFCI.
 
... one of the original circuits on the main level, that I hadn't even touched, started nuisance tripping.

Troubleshooting that issue wasn't in the bid even though I resolved it.

And was the breaker actually telling you there was a real problem that needed correction? Or was it the usual reason?
 
Not sure I agree with that simplified perspective...

It's common to have a culmination of events that lead to a nuisance trip, not just one light, or one particular vacuum, but maybe a mixture of the loads. And even then it's not consistent enough to pin down the sequence of events that causes the nuisance trip.

Heck, I had one house recently that was a manufactured home that sat on the foundation for 3-4 years with everything working just fine, then when I went and finished out their basement (requiring added AFCI breakers in the panel) one of the original circuits on the main level, that I hadn't even touched, started nuisance tripping.

Troubleshooting that issue wasn't in the bid even though I resolved it.

So how do you fix a 'nuisance' trip?

My last solution was to swap the circuit wires with the AFCI next to it, as one particular bedroom light seemed to be the trigger.

So far, I've not heard back, and that was over a year ago.

That's an elegant solution to NEC load calculations for bedrooms, along with one 20A circuit for each bathroom.

Rooms w/ small appliance heat & air can run 20A homerun to line feed appliance outlet, to 15A-fused #14 cable loads to lights & switches.

Load calculations is a different issue. The four bedrooms might be total 600 square feet - which per NEC would be 1800 VA and could be handled on one 15 amp circuit. And unless you have portable heaters or window AC's used probably is going to have little issues in most cases.

Them box cover units are not listed branch circuit devices
 
I have been doing it for years, and not for those devices.

I'm with Larry. I grew up in a 60 amp service house with Edison base plug fuses, all four of them. So, when the vacuum cleaner or kitchen appliance blew the 15 amp fuse, you were in the dark. Not going to happen to me or my customers again. I know, many more circuits in houses now, and 20 amp receptacle circuits are common, and "blowing fuses" or breakers is rare, but I build like I live there!:thumbsup:
 
Working for companies I wired hundreds of homes in the 70’s, and except for the customs every house got the bare minimum. Back then it was even typical to put only one 15a GFCI breaker in the panel and have it supply every bathroom, outdoor, basement, sump pump receptacle in the house.
30 years ago I wired my own home and besides several 3 and 4 way sw’s, a lot of permanently installed lighting, ceiling light outlets in every rm, a 3rd SABC and not using stabs I didn’t do anything else beyond minimum and I don’t recall ever tripping a breaker.
So it’s surprising to me to hear about all of these above and beyond methods. Maybe it’s just a different economy, but I know one thing for sure, if I’m in my bedroom with the ceiling fan, lights and TV all on I could probably have my laptop and phone plugged in too and still not be using more than 2 amps and that’s only 17% of a 15 amp lighting circuit.
 
I see you do not iron clothes in your bedroom with the wife saying it is cold in here, plug in the 1800 watt heater......

Happens in my wife's sewing room [which is a bedroom] all the time, ceiling fan with lights on, portable lamps on, sewing machine running, iron plugged in, cycling and the toe kick heater cylcling also. Lucky, three different circuits.;)
 
Since AFCI’s became mandatory, and given the fairly common issue of nuisance tripping, we’ve wired a 15amp circuit to each smaller bedroom for lights and receptacles, and a 15amp for receptacles and another for lighting in master suites, using the lighting circuit for the bath lights as well. Very few call backs, and 99% of the time the issue is an occupant owned device that the AFCI doesn’t like.

In my case if I or my wife used a bedroom as a hobby area like that, I'd have to run a dedicated #12-3 to it! I probably would grumble a little bit about that 1800 watt furnace, but just a little bit.:hug:

It is crazy that the AFCI is causing that much disturbance. I bet many are replacing them with regular breakers, similar to years ago when people would put pennies behind their plug fuses.
It may not ever be possible for the AFCI's algorithm to distinguish between a TV advertised vacuum cleaner, that can suck up a bowling ball, and still be an effective safety device, but if consumers can get a better understanding of it, maybe appliance manufacturers will eventually be pressured to arc fault certify their products.

Consumers still don't understand GFCI's. I don't expect all that many to ever understand either. Most just see it as that thing that trips and then things won't work but have no idea why. You can explain all you want, all they care about is to make it stop tripping.

That is a good idea. I wonder if there is any testing done as part of the listing of the product.

I was reading a comment just the other day where a homeowner was complaining of an AFCI tripping and he replaced with a regular breaker and the problem stopped so he gave himself a pat on the back for being so smart.

I don't think there are really as many problems with AFCI breakers as many people are led to believe. The problem with AFCI breakers is that when there is a problem it can be harder to find than when working with standard breakers. The reason I say this is I often see a whole panel of AFCI breakers and the owners have never had any problems. If the breakers were the problem they should be a problem for everyone and not just certain homes.

I mostly agree, problems typically will be in the wiring or even equipment that is not in proper working condition.

There still is occasional equipment that doesn't play well with AFCI's though.

One would like to think that, but there are problems with them and a major part of the problem is the inconsistencies in their operation. It is a 100% fact that they nuisance trip and it is a 100% fact that manufactures knew about it.
