I also ran dedicated lines and am glad I did. Besides the dedicated 240V line, I decided to run to dedicated 120V lines. I also had a small, in the in-wall mounted breaker box installed so I could remove all equipment power without losing the existing power. This allows me to use the room for other things. All this cost me less than $300 for materials since a friend who was a Master Electrician before he got his current electronics job volunteered to help me out. I was worried about having the breaker box installed in the room, looks, etc. But I feel really good about it now, because Electrical Inspections require that you have good access to breaker boxes and that they are not installed in busy closets and such. Later, I discovered that the wall power I had been using was wired into the GFI breaker in the guest bathroom. This thing has kicked out from non-radio activity things and I could just see this happening in the heat of a contest, etc. 72/73 & DX, Craig W. Behrens -- NM4T
