Box to small can I remove ground wire ?

Just installed a ceiling fan (Brand = Craftsman by minkAire) with which has a wall transmitter to adjust fan speed and light. Everything works fine BUT the wall transmitter won't fit in the existing two gang box (which is 1950s' vintage and metal). The ground wire is attached to a tab (about 1/8-1/4 inch thick) on the bottom of the transmitter and the transmitter won't fit in vertically because of this tab. Any thoughts on how I can keep the old box or am I going to have to cut it out and replace with a new one ? If I have to do the latter I would appreciate any step by step directions that can be provided.

Thanks in advance....

Is this a switch box on the wall or the fan box on the ceiling? A picture might help us understand.

A picture of your wall box, open so we can see inside, and a picture of - or link to - the transmitter you have will help us see what you're faced with. See How To Include Pictures.

Box to small clarification

It is the gang box on the wall... The line coming in from the circuit breaker (which is a 20 amp) is a 14-3. The neutrals (white) are all tied together and go their individual devices. The incoming black (hot) feeds a light switch that controls two lights on the wall. The red (also hot) is wired to the black wall transmitter input wire and the transmitter output (load wire) is connected to the fan wire which controls the both the fan and its' lights Here is a link to the fan and what the external of the wall control looks like...

You cannot have 14AWG on a 20A breaker. You either need to rewire your circuit or replace the breaker with a 15A one.

That is a multiwire branch circuit, or MWBC, in which two hot wires share a neutral. The two hot wires need to protected by a pair of adjacent breakers tied together with a handle tie. It does not have to be a two-pole breaker, which provides simultaneous tripping, but must provide for simultaneous opening for servicing.

As already stated, if the wire is 14AWG, those breakers must be no larger than 15A. Ideally, they would provide AFCI (Arc Fault Circuit Interruption) protection as well. What room are you working in?

That's a very nice looking fan/light combo. But your question was about fitting the wall controller for it into your switch box. It will help us help you do that is you can show us the back of the controller and the inside of the switch box.

Update....

Sorry... the wire is either a 12 or 10 gauge... Also here is a link to the controller
unfortunately it only shows a side view (wires, dip switches, etc.) but it does not show the tab on the bottom where the ground wire is attached (the picture implies it is on the right hand side -- when looking at the controller from the front) BUT ....looking at the front of the controller then the tab would be under the left bottom side of the controller, connected close to the face plate and extending about an inch backward. Have had trouble trying to load picture of box -- sorry..

STEP 5 HAS THE DRAWING OF THE CONTROLLER..

I would really like to see a picture of the wall box. Devices and boxes are standard sizes so it should fit in the box.

Not sure how that will help. As pcboss said,

Well, it's probably one of those sizes. How are you determining the wire size?

Regardless of the wire size, that is still a multiwire branch circuit, or MWBC, in which two hot wires share a neutral. The two hot wires need to protected by a pair of adjacent breakers tied together with a handle tie. It does not have to be a two-pole breaker, which provides simultaneous tripping, but must provide for simultaneous opening for servicing.

Is this the type of box you have.



The red (also hot) is...
With a multimeter measure the voltage between the black and red. What is it?
