TRCTechnology Research 44750 Surge Guard 30-Amp with Ground

Q: What is the clamping voltage, the joules rating, the response time and does the indicator light mean it is providing surge protection or just "on"?

On the "Technology Research Website" they give some specs but the not the most important "clamping voltage" which I found through reading various sites. The joules rating is 510 but a low joules rating is not necessarily an indicator of an inferior product as wikipedia's reasonably good article discusses. Response time is usually very good for MOV types as I think this is since MOV is the least expensive design (wikipedia again:) Thats what I've learned so far. This product also looks more promising than the similarly priced & rated product that doesn't claim protection but only says "Surge Status Indicator" So I haven't decided to buy yet myself but hope the info helps others who are interested. P.S. I just called tech support at 800 780-4324 and was told the clamping voltage on this model is 700 volts. I have read that 400 or less is best on some sites about surge protection. The manuals for their other models show a lower clamping voltage and may be better.

Q: Does it detect & report low voltage?

No. High voltage protection and Ground Fault only. See the comparison chart at http://www.rvupgradestore.com/Articles.asp?ID=279

Q: Does it kick off and stay off or will it come back on by itself i use my rv for work and i’m not there with it all the time

on mine it kicks out and stays out till you reset it. so far i have not had any trouble with mine. pretty fool proof.

Q: does it tell you if box is wired wrong

No. It will detect ground faults, but not polarity. You still need your volt meter. I did find this listing comparing different Surge Guards that includes this one: http://www.rvupgradestore.com/Articles.asp?ID=279
