My new 10-way powerboard arrived today and I wired it into the booth along with a PowerShield Defender 1200 UPS battery which I had spare.
Then I had two spare powerboards so I installed one of them (with an RCD Safety Switch) behind the bench. You can see it in the photo below. The thing you can see plugged in on the top is my Watt Meter, it reports on current draw and power usage.
I am pretty happy with today’s handiwork.
