Just want to clear up a bit of confusion. If you’re unsure of which of our plug in Galvanic Isolators to get, the answer’s simple. You choose the one with the correct size plug.

The 16a is no less “powerful” than the 32a. The only consideration is the plug size. So just measure the plug on your mains cable, and compare with the measurements in the photo. Easy as that.

The VAST majority of marinas have 16a supplies, but it’s worth checking – just to be 100% certain. Hope this helps.
