surge protection of subpanel
We have a main panel in our house (200 amp) that has an Intermatic PanelGuard (surge arrestor) attached to it at the base.
Branching off the main panel is a subpanel in our pool cabana. Since the subpanel is wired to the main panel, it doesn't need its own surge arrestor, does it?
Thanks.
Dave

I would say no. Typically your main panel does not require a surge suppressor. However, it does help protect the electronic systems in your house from surges and such. I put one on my main panel to protect things like the TV, microwave, stove (electronic controls). As long as there is no major electronic devices or such in the cabana. But the arrestors are relatively cheap compared with replacement of some items...so It might be cheap insurance.

Well, there is the system that runs the pool. It is all computerized and cost approx $2000. I would install an arrestor if needed, but I thought it would be overkill.

How is the power run to the cabana? If it is overhead, the lines could take a lightning strike. Just regular power line surges will be handled by the main panel's surge arrestor. If there is little chance of a lightning strike between your main panel and subpanel, I probably wouldn't worry. If the lightning strike is an concern, an individual lightning arrestor could be added to the sub with minimal cost.
