I'm looking for compatible breakers for my old ITE Blueline Loadcenter main panel. I believe ITE was bought by Siemens. Would the Siemens 100A 2 Pole 120/240V Type Q Breaker (https://www.homedepot.ca/product/siemens-100a-2-pole-120-240v-type-q-breaker/1000436969) be compatible for supplying 100A sub-panel?

Update: I noticed one newer Siemens breaker in the panel! It's labelled type BL. Can I assume all type BL breakers will be compatible with my ITE Blueline Loadcenter panel?

Update: Photos added.

  • Can you post photos of the labeling on the inside of your panel's door please? Oct 10, 2020 at 3:07
  • well unfortunately there is no labeling on the inside of the panel's door... or anywhere else on the panel

You are looking for a Siemens BL2 (not to be confused with a Siemens BL)

ITE Blue Line loadcenters appear to use a special style of "thin" breaker instead of the more "typical" QP (EQ-P) breaker. Unfortunately, the ITE Blue Line (not to be confused with the other type BL breaker, which is the bolt-down version of the QP and thus no use to you), only is available in 1 pole up to 50A and 2 pole up to 40A, as per the current Siemens Canada catalog. So, you'll either need to run a smaller feeder to your subpanel, or have your main panel replaced outright.

  • ouff... I was hoping to future proof for possible solar (I think I need at least 60A 2 pole for that) but I guess that's a future problem. The 40A is more than enough more my current needs. Pun not intended.

  • follow up: the BL2-040 is the 2 pole 40A breaker. So I need the 8/3 wire for that?

    @jpx -- yea, that'd go with 8/3... Oct 12, 2020 at 0:32
