Hi - I recently installed a timer switch for my front porch light. It seems to be working fine. However, after installing it I noticed the package said "for use in double gang box." I have it installed in a tripe gang box, along with a conventional light switch, and a three-way light switch. Is this something I really need to worry about?

Thanks much.

Probably not, but if you can provide the make and model I can check.

Thanks! It's an Intermatic 15 Amp, 120/240/277, 7-day Programmable Time Switch, model #SS8C.

Sorry but can you tell me where in the instructions it states that "for use in double gang box." ?

Hello again, and thank you for your continud help. I'm very sorry, but I gave you the wrong model number. It's actually the EJ500. The install manual is here:

On page 1 under "Important Notes" it says the switch is suitable for use in up to 2 gang installations. I believe it says the same on the package exterior.

Thanks very much.

OK I see, what is the total load of each switch circuit in the 3 gang box? They are concerned with the load this timer can handle, and the heat it will create.

The first switch is a three-way switch connected to an interior ceiling fixture containing a 75 watt bulb; the middle switch is connected to an external motion sensor light with 2 light bulbs (unsure of wattage, but I'm guessing 75-100 each); the third switch (the timer) is connected to the overhead porch light containing a 75 watt bulb.

Continued thanks...

Even though you are not following the manufacturers instructions, I don't think there will be a problem. Best to monitor the heat that the timer may create, and if you ever move, remove the timer so there is no chance of someone else having a problem because they are not aware.

Really would be better to replace the timer with something that can be installed in a 3 gang switch box, and not violate the instructions, the risk is all yours.
