Installer was insistent that the receiver and power inserter not be plugged into surge protector. Said they must be plugged directly into wall outlets for MRV to work. Is that right? Seems risky.
Surge protectors can be used to power anything we use. They're pretty much useless. I've been using them for years and I've never had one protect me from surges. I even called Tripplite and asked them about using surge protectors after the UPS, which is not recommended on the Tripplite box, and the Tech I talked to said he had no idea why that was on the box, but he did say using an SP with a UPS was overkill and a waste of money.
, I use the SPs because of the configuration, don't expect the SPs to really do anything.
Remember, if an installer was an electrician, he wouldn't be an installer. The advice he gave you was useless (I am an electrician).
