Surge Protection Help, Is This Safe?

[OliverKlozoff]

Hello, everybody. I'm looking to hook some surge protectors up to my 240v gavitas as a wind storm the other day tripped some of my magnetic ballasts. I've read every thread on surge protection here I could find, but am looking for a removable set up. I was thinking of using one of these per light

plugged into my digital 240v timer using one of these adapters

each timer is currently plugged in to its own outlet that looks like this

https://www.google.com/search?q=240...hXTLIgKHSNoDGsQ_AUIBygC#imgrc=R4eZz3wUWhf5SM:

There are 3 outets per 30 amp dedicated 220-240v breaker.

My questions are will the 450joule(watts) rating protect from the average surge? Will the surge get distributed over the multiple strips or just blow the first one in line? Would it be wiser to plug the timer in to the surge protector rather than the protector in to the timer? I'd rather blow a timer and a protector than a ballast.

I've looked at trippe lites stuff and didn't see any with the plugs i'm using. I also believe it would be better for me to use one protector per outlet because the outlets may only be rated to 10 amp like these protectors. I'm trying to avoid new outlets or any sort of hardwired protector in the line as these would have to be removed eventually or used for the whole house panel. I'm not an electrician, so my guy would have to come out multiple times which my neighbors will ask me about. Thanks for any suggestions/info.

I use a surge protector with every timer, light and fan combo's each have their own timer.
The brand I chose shuts down if the joule rating is exceeded, keeping the pulse from reaching further.
Here in Alaska the power goes down quite a few times each winter and about one out of four sends a spike that overwhelms a surge protector.

I reread your post and noticed I did not address the main question.

I use 450 to 900 joule protectors. When I used the tiny 200 joule protectors they were overcome with small spikes and needed replaced almost every power outage.
Spikes large enough to blow a 900 joule protector also blew 2000 jole units so I went down in size until the balance between protection and cost was found.

Here where I live most outages are trees shorting out trunk lines resulting in relatively low voltage spikes, or diesel generator spikes. Areas where lightning strikes happen would require a different class of protection as would industrial areas with three phase running in parallel on the same poles.

The smaller the rating the less voltage required in the surge to blow the fuse.
Lightning strikes will blow the fuse on any unit regardless of rating.
High joule units cost more, low joule units need replaced more often in surge prone areas.

Diesel powered backup generators are used during outages that outlast the battery pack (A prideful note here, the battery pack is the largest in the USA and will run 15,000 homes for 15 minutes).
The diesel output is cleaned up pretty well, but one in four outages does result in a blown surge protector.

The protection needed depends on the power supply in your locality.

Thanks, sounds like these rated@450 should work as we don't have surges often around here. Where do you buy your 900joule ones?
