Default Meter brand for Onan panel

Hello,
Maybe i am over thinking this but i finally order the natural gas parts and want to start building a "box"
I was just going to use the cheap digital china meters, but it had me thinking, they used "normal" mechanical meters for ever so are they a lot better?

Also on the digital china ones are there any brands that are better than others?

I dont want to spend 50 bucks on one meter, but i dont want them to blow either.
Any experience/input is greatly appreciated.
As always thank you all very much,
Dave

Dave, those meters in your JC are typical meters found today on the internet made by Drok. They are cheap in price and work well. I posted a link below.

As you are aware of, I made many JohnnyC kilowatt boxes using Drok meters. For my latest JB project I am using OEM brand (Yokogawa) big analog meters for 1 primary reason and that is to keep the JB original as much as possible, but I will still be able to use my JohnnyC kilowatt box too. The assumption is that my JB came with the meter panel and I have not seen many JB with this option so I want to preserve the looks and functionality.

Thank you JohnnyC,
I will just use those meters, they seem to work very well.
crazy question, do you happen to remember what the electric box is called with hinges on the side (like you used on the JC)
I found a lot of boxes, but most are "screw on" covers

Thank you,
Dave

eBay is overrun with meters. I have bought a number of them for under 20. The vibrating reed frequency meters go for more but I think they are very nice looking.

When I had my IT job in the telecommunication company where I work for 28 years, at the time our new owners took over (Ericsson) and started outsourcing the US based offices overseas to Urkraine and India including my entire department, there was a huge cleanup. I got that box from one of the labs during the cleanup. It is of high quality and most likely you and I won't find another like it. If I had another I'd give it to you. The boxes I use for the JohnnyC kilowatt boxes are purchased at Home Depot in the electrical department.

I found a simplified wiring diagram version for my JohnnyC kilowatt box from an old subject I posted for the 4.0 BFA (see below). The BFA was 120 vac only, and yours is 120 / 240 vac so it will be different, but as you can see by my beautiful and well laid out wiring diagram these boxes are easy to build and use.

I realize that this is not really comparable, but many years ago, back before I could legally drive a car, I built a dune buggy. At the time JC Whitney carried "Cyberdyne" red LED digital gauges, and I thought that they looked REALLY sharp, so I bought a FULL compliment of them, and custom built an instrument panel for them. Well, they really did look neat, but, as it turns out, they're totally impractical to use while driving. It turns out that it takes DRAMATICALLY less time for the brain to register the position of a needle and compare it to normal than it takes to read a number and interpret it's significance.

In the "old days" all the Analog meters used D'arsonval meter movements with jeweled pivots, just like quality watches used. Nowadays virtually all new Analog meters use what is called a "taught band" design. Vanman is correct that the eye responds quicker to an analog meter, but in terms of reliability the taught band meters just don't cut it.

When buying Chinese digital amp. meters, pay attention to the CT coils. Some do not include them. Some are attached to the meter board which is not very substantial, making it hard to route heavy wire through them without damaging the meter board during assembly and with movement. Some do not have a large enough hole to accommodate #6 wire.

I look for meters with separate CT coils, with large enough holes to accept the largest wire I might use. I have found the leads on most of these to be extremely fine stranded wire (30 ga. ?) that can be a PIA to connect to anything.
