Double surge suppressors would rise some questions most places some clients have very strict standards that must be followed others don't care what you do.
Most who recommend a surge protector only do so because wild speculation, brainwashing by hearsay, subjective accusations, and total technical ignorance has recommended it.
What dogleg43 calls too much time and too much money is, in reality, done in seconds or minutes. Resulting in massive cost reductions. But too complicated and hard for one who has never done this stuff. Who makes conclusions anyway (as taught in business management school).
A first time designer may take an hour - to learn how to be an informed designer. Then future designs only take seconds or minutes - to do what dogleg43 only wildly speculated as too much time and money.
Nothing says he needs surge protectors. In part, because relevant fact were never provided. Others, using only what they want to believe, will make recommendations. Rather than state what parameters are required to have an informed reply.
Had he selected a correct part and output, then no surge protector parts are required. How does that happen? So many parameters are learned long before making any design conclusion.
Most inspections are only for human safety. Surge protectors are for hardware protection. As EMILLER233 so rightly asks, "What does surge suppression have to do with an electrical inspection..."
Hardware protection is found/verified in design reviews. What does a design review always need? Those parameters. A design review demands parameters - so that hardware does not fail. Completely different purpose from an inspection.
OP has the only possible answers - because he did not even state if those were AC or DC coils. The electrically naive are always quickly identified. They complain it is too hard rather than learn why this stuff is always known (read and learned).
This is America where a music major is now head of computer and other security for a major credit reporting company - that has all our private information. And released that data to hackers. Why? She also could not be bothered to learn parameters or how things work. She was a music major. In many places, that alone means one can make expert recommendations - by using speculation as if parameters.
