Wall boxes for Insteon SwitchLinc Dimmer 2477D

[kfp22]

Hello, I am trying to find some wall boxes for Insteon SwitchLinc Dimmer 2477D.

For 1-gang, I found this which is 2 13/16" Deep: http://www.smarthome.com/14-cubic-inch-zip-box.html

However, for 2-gang and 3-gang, it seems that all those on Smarthome.com are much deeper than the 1-gang above. (at least 3 5/8" deep)

Is it because to place two or three 2477D together it requires more depth, or is it just that the 2 13/16" boxes are not available on Smarthome.com?

Would these wall boxes on homedepot work?

The first and third boxes you linked to are old work type boxes. Where you cut a hole in the wall board and push it into the cutout. When you turn the two mounting screws the ears pop up and hole the box into the cutout hole.

The second one you linked to is a new work type box. You use the nails on the side to mount it on a stud to hold it in place. Then when the wall board is installed. A hole is cut in the wall board so the box sticks through.

Deeper boxes have added room for wire routing and switch depth. Most recommend deeper boxes for easier installs.

Metal electrical boxes will help get any heat generated by the dimmers out of the dimmer so it runs cooler.

Also two 2477D Switchlincs next to each other. Have to have their maximum wattage rating reduced by 200 watts. So each one would be maximum of 400 watts not 600 watts.

If you are going to be using any of the SwitchLinc On/Off modules. They are deeper than many other modules and a deep box is almost always needed.

BLH, Thanks again for your quick help! Really appreciated as I'd have to place an order by tomorrow to not further delay my contractor's schedule.

Indeed I would like to get a box as deep as possible, only that the walls in my apartment can only allow 3 inch max deep of a wall box (thats as deep as my contractor is willing to do anyway)

1) From smarthome.com, the stated depth of 2477D dimmer, 2477S on/off switch are both 1.2" inch. Is it this 2477S On/Off switchlinc that the one you mentioned are deeper than the rest?

2) Do you think the new work type box in my second link is deep enough to fit 2477D switch links? (Aside from a bit of extra effort to manage the wiring inside)

3) For metallic box, I had the (probably wrong) impression that the metal might interfere with the RF signals. Would it not?
I found these metal boxes on homedepot but they are 2-1/2" deep, do you think 2477D and 2477S would fit in? (http://www.homedepot.com/p/Raco-3-Ga...-692/203634429)

1) I just looked at the sales pages. The 2477D is 1.2" deep, 2477S 1.47" deep. The On/Off version is slightly deeper and is the one I was talking about.
The 2477S also has #12 Black and Red wires since it is rated for 17 amps. So the wires are harder to bend to they fit in the electrical box.
2) Should be deep enough.
3) You brought out a good point I forgot about. Yes the metal boxes will limit the Insteon RF performance. As the antennas for the RF are near the back of the module.

All clear, thanks so much. You guys here in the Insteon forum are the best!

All my boxes are metal. I have no communication problems.

Good to know, stu !

NEC table 314.16(A) will list all standard electrical boxs. Here is a good link below for sizing a box and keeping in code. As you will read in the link it is vary easy to over fill a box. Remember when working with metal boxes you will need to install a mud ring before the wall broad is installed, this will increase your box's cubic volume.

There are metal boxes that do not require a mud ring, like these, for example:

BTW, you can use a masonry box in a non-masonry environment.

Will 2 Insteon switches normally fit in a standard 2 gang electrical box? I replacing standard on/off switches. The fit width wise seems to be very tight & almost have to force both switches into the box. I looks like the toggle dimmers have a slightly smaller profile. Just don't want to cram two 2477D's in the box & have a issue.

Depending on the boxes the contractor installed, it mat be a tight fit, but yes, if it's a2-gang box the two Insteon devices should fit. You may need to tuck the wires in very carefully or even cut the a bit shorter.
