I recently bought a Siemens 30 amp 120/240 volt disconnect switch. And it has plug fuse plugs. But I don't want to use a fuse. I want to use a mini breaker plug. But I can't seem to find one.
It's a Type 1 enclosure. I am looking for a 30 amp mini breaker plug. I will most likely overload the fuse so mamy times that it wouldn't be worth putting a fuse in in the first place. So I need a 30 amp mini breaker plug.
The disconnect switch is my new safety switch for my highly dangerous and high power output applications. So you could see how I could very easily overload the fuses and prefer a breaker instead.
This box will act as a disconnect switch cutting the power to the load. This switch will get its power from either 20 amp outlets or 30 amp outlets. Both are on 125 volts. 30/125 and 20/125. It's a better version of my old safety switch. But this switch is inline.
Does anyone know where I could find a 30 amp mini breaker plug rated for 125/240 volts AC?
Something like this one, but 30 amps and not 20. lowes.com/pd/Cooper-Bussmann-20-Amp-Fast-Acting-Plug-Fuse/…-c--prd--rpe--google--lia--206--switchgear--1269477-_-0&store_code=1133&placeholder=null&gclsrc=aw.ds&&gclid=EAIaIQobChMI7JGV6Yji5wIVzZyzCh2ZOQzpEAQYAiABEgIoofD_BwE
And a breaker, so not a fuse.

@ScientistSmithYT I wouldn't use the plug fuse model anyway for this application
I'd take it back and get the version that uses cartridge fuses (a GF221NA instead of a LF211N)
 
I have a question about digital signal timing but I don't know some words so I'd like to ask here:
As far as I know, there are 2 ways to represent bits:
1. High (5V) = 1; Low (0V) = 0
2. Presence of rising/falling edge = 1; Absence of edge = 0
How should I call the 2 ways bits are represented and timed?

Bits are always represented in a binary fashion - off/on, 0/1, low/high, down/up, whatever. The edge transitions are always just that - high-going or low-going. They either go high, or go low. Often, something happens as a direct result of an edge, such as the clock on a flip-flop changing it's state.
Also often, a device will wait a predetermined amount of time to read a digital signal. Such as an RS232 serial device - once it sees the start bit, it counts to half of the baud rate then samples the input wire, so that it's sample is right in the middle of when the data bit is sent.
Well technically 1.5 times initially, since the start bit is a known state, and it wants to get the following bit.

@Shalvenay Ok. I actually don't want to use a fuse. I want to use a breaker instead of a fuse. So I was wondering if they have a 30 amp breaker plug for my disconnect switch.
@Shalvenay I thought I'd probably blow the fuse too many times that the cost for fuses wouldn't be worth it. So I want to get a breaker plug instead. Since those would be cheaper than a one use deal like fuses.
