Laminar Jet Electrical Safety

Post  jetty on Fri Aug 12, 2011 1:47 pm

I'd like to start a thread on electrical safety in laminar jet installations as I haven't seen it discussed previously. Dealing with water and mains voltages can be deadly. Also, people love playing with laminar jets, don't kill em.

First off a disclaimer, I'm not a qualified electrician, so please contact one first. Also, some locations (most) would require you to do work to code, have it inspected or get a qualified electrician to do the work for you, check your local rules.

Here are some things I've initially thought of, please add to the list:

1. All power delivered to the project should be via an GFCI / RCD. Either on the power socket, fuse box or via an inline device. The power supply should be earthed and bonded. GFCI's / RCD's should be tested regularly.

2. Earth pins should never be removed from any leads / plugs used in the project to make it fit a socket.

3. Supporting electronics should be fused with the correct fuse.

4. Any metalwork in the project should be earthed and bonded together. Verify it's bonded with a resistance checker on your voltmeter.

5. Ensure the laminar jet can't soak any electronics / sockets or electrical connections.

Use a GFCI (google it if you don't know what that is).

Use an isolated power supply.

GFCI = RCD for those who don't know. Commonly known as GFCI's in the US/Canada and RCD's in some other countries (mainly Europe).
