Re: Lighting loads
The dimmer can be ran at 100% rated load- a 2000W dimmer can be used since you will only be at 90% max. Some manufactures make a 2400W dimmer, if that makes you feel better and the architect appoves of the looks. They are big and ugly. Pay attentiion to the manufactures derating for ganging, if applicable. The dimmer will feel like a small room heater when full bright so, as stated earlier, give the dimmer room to breathe around the front plate- ask about plans for fabric finish on the wall that will trap heat. Make sure that you are not sharing a neutral for the supply circuit. The dimmer will likely have a short life compared to others more suitably loaded at 80%.
