I just ran across a very unusual situation. I was inspecting a 200 amp C-H main service panel and there were two unusual items mounted to the side. They were Delta surge capacitor M/N CA302-R and a Delta lightning arrestor M/N LA302-R.
Now the fun part. They were triple tapped to a 30 amp 220 VAC breaker (One on each leg). The feeders to these products are about AWG-12.
I went to http://www.deltasurgeprotectors.com/installation.cfm?installmod=7&page=3 and the manufacturer’s instructions show to do this. The reason for the tripple tapping is each unit has two “hot” leads (one per leg) and there were two separate units.
- Shouldn’t they be pigtailed since the last I knew C-H breakers are not rated for double taps besides the fact the wire gauges are different (A big No-No)?
- Does this product even work?
