Will it hold 40 lbs? #210514 07/05/13 09:30 PM

I accepted a job replacing a few customer supplied lights in a new condo. The customer asked if the box would hold 20 lbs and "what about 40 lbs?" That's not a code question. That's a question of fact. Did the installing electrician do a good enough job that the box will hold the weight.

One light was over a granite-topped island.

So, for a couple hundred dollars not only do I install the lights, but I guarantee the box is solid, replacement of the counter-top if it happens to get damaged and replacement of the light if it gets damaged. I'll bet you couldn't buy that kind of insurance for a couple hundred dollars.

Maybe what bothered me was taking a crappy light down three times to adjust the height from inside the canopy. Maybe it was spending an hour unwrapping the first fixture because it gave me too much time to think. I think installing residential lights exactly 29 inches above the counter is the low point of my job.

Well, now you've learned. Next time, price accordingly.

You raise a good question about having liability insurance, for the time something does go wrong. I don't always have a couple grand sitting around, to replace a cracked counter.

Your customer always has the option of hiring Handy Hank from the box-store parking lot. Let the customer take the hit of replacing the counter if Hank's efforts fail.

I have the insurance but I don't want to use it that way. It's so the customers who support my business have a guarantee that if I screw up, they will be looked after.

I'm going to pass on this type of work except for existing customers. I'd rather drink beer than discuss the difference between a light over a bed at 72 or 74 inches FFF.

A "fan rated box" will typically state a rating of 70lbs for fixture support IIRC. I've hung a 35lb chandelier from one before and it seemed pretty stable. Anything super heavy is going to be lagged into a ceiling joist if I'm doing it.

Lighting can certainly be a royal pain. When bidding construction I always put in my bid that we will install "standard" fans and fixtures provided by the customer. "Non standard" fans and fixtures are charged extra at an hourly rate. As far as who determines what is "standard", that would be me.

IMO, weight ratings on boxes are pure eyewash.

I say this, as they do not address the box attachment,or what is supporting the box. Since you often can't access the framing to inspect, it can be a gamble.
