I have an petrol generator to charge the battery in my caravan. To try and give better protection to under/over voltage to the charging system in the van I purchased a voltage protection plug and have used it to give me peace of mind. Am I wasting my time or is this a good unit? For spec's on the unit look at www.acdc.co.za, goto catalogue page 83, bottom of page is the data on the 15A Voltage Protection Plug.
Any comments on unit?
