I have two P20’s. Each on it’s own dedicated 20A sub panel.
One of them believe it or not I not only used all the outlets, I used all the outlets in a Dectect into it via an AC12. I know about the impedance issue. It must be this one or the components will not reach where I want them. I will use another AC12. Any Fire Chief would say no way. However, they may not recognize the P20 is not a “mere” power strip". You certainly cannot safely “gang” power strips for that matter. These are just low power Wallwarts. It is only at about 70% absolute maximum. Normally about 30%. So it is far from overload. I was just wondering if there is any reason I do not know of that this is not safe? I could use the other one with the longest AC12 but $$$ comes into play. It would be best if Paul answers but anyone is welcome to. Thank you
I am certainly no fire chief, but using a Dectet on the outlets to extend the number should be safe. You’ll want to make sure you’re using safe components, like the AC12 (and keep the ground pin intact), but it sounds like you already are. Adding a second should be no problem.
You mean, you don’t have plan to get another P20 and install another 20A dedicated? 
Thank you Paul. That is good news. I asked you because you actually understand your product more than a Fire Chief. It is not just ganging Power strips together which is in fact a big no-no. I like the higher impedance. Which must be why I like the P9x too. The P20 is indeed a more sophisticated machine. Which is why I continue to use them for reference. My “little” system I did replace the P12 with a P9x but no offense meant. Just a preference.
Recently an Electric Engineer witnessed this. He informed me that to put a device containing MOV’s in front of another device also utilizing MOV’s in the electrical pathway could prove dangerous and is in fact in violation of the current NEC? Any thoughts on this? Of course he told me I can do as I please in my own residence but in the highly unlikely event that it burns due to this my insurance may have a legal “out” not to provide me with coverage on it. I am not entirely sure how or why this could be a possible risk but then again I am not an Electric Engineer either. He said most likely it will function without incident but it only takes once… My understanding, Paul was that you told me this was okay. Since you are indeed the manufacturer of this equipment, is he simply misinformed as to this? Thank you
Edit: I have reviewed the manuals of 5 well known surge suppressor strips and power taps from readily available consumer brands. They all state something to the following effect:
Do not plug this unit into a battery backup or power conditioner.
Do not “daisy chain” units.
These are not PS Audio components.
I really need to be able to do this but I also want to stay safe of course.
Paul, Since you are the manufacturer of both components in question I am going to utilize your advice pertaining to this matter. I will assume that you have the correct knowledge of your own products.
I will further assume that doing so is indeed safe in this instance. In all likelihood nothing “bad” ever arises out of this scenario regardless. I was already reasonably convinced of that myself. Thank you for confirming such. I have another Dectet and AC12 enroot this afternoon. I shall then be all set.
Thank you, consider this to be resolved.
Hi @Paul,
Doesn’t the Dectet adds back some impedance to the extremely low output impedance achieved by the P20? In that case, while there’s no functional issue, wouldn’t there be a (hopefully small) performance penalty to attaching a component to a Dectet (plugged into a P20) outlet, as opposed to attaching it directly to a P20 outlet?
Which makes me wonder whether an expansion block that has no filters, MOVs, etc. would be the preferred method. What I don’t know is whether such accessories exist. Most expansion strips are designed for standalone use, so tend to have some protections built in.
