Thanks, that is what I believed but it is good to hear someone else say it.
I ended up with a 60a rated disconnect too since the breaker in it is 40 (per the O/C device spec on the label).
In a disconnect without O/C protection I agree with those who say you will need one that is HP rated, like any other disconnect. I fear a "30" might be aimed at water heaters if it is not specifically labelled with a HP rating. If it is thusly labelled, go by the label. I am sure most pullouts can open LRA but you should be wearing gloves and sunglasses
