  1. How many slimline (THQP) double poles can I have?

    Hi all, I have a GE TMC4020CCU Powermark loadcenter (Canadian model) with 40 spaces. The circuit diagram indicates that it can take 80 1/2" breakers (THQP) in any position. But it then says the maximum number of 2 pole THQP breakers is 38. What I don't understand is why this number is not 40...
  2. Mapping house electrical circuits with tandem circuit breakers

    We have an older Square D panelboard fuse box with Tandem breakers in it. I want to do what I call a "wire mapping" for the whole house and create a sheet of info as to which outlets/switches go to which breaker. When I open the panel for example, each circuit breaker has a number next to it...
  3. Handle Tie Clip to Connect Single Breakers

  7. Tandem loaded truck over soft lawn?

    Landscaping & Lawn Care
    I am trying to get a lot of dirt into my back yard to fill some low spots. We tried to drive a fully loaded tandem dumper over my lawn but the soil is so soft that the truck just started to sink in. The driver said that he wasn't going to go in for fear of getting stuck. So now I am not sure how...
