How are your appliances connected

[toggleswitch]

Thank you boys. I'm delerious with delight!

~One must therefore always check (the wiring) before inserting a (Perilex) plug in an unknown socket.

You know that is EXACTLY what we do here to be safe and live longer, too..........

 

[toggleswitch]

In panel/post #272091 "A" cord for Perilex.

Brown + blue = 1st circuit?
Gray + black = 2nd circuit?
Green/yellow of course is earth / ground

in 3-phase applications would it be......

Blue= Neutral?
Brown = phase 1?
black & grey phases 3 & 4?

In Europe/ UK:
(BL)ue was (BL)ack => neutral?
Brown was red => hot?

In the U.S.A we have: 110/220v or (110/208v)
White= neutral
Black= hot (or hot, phase 1)
Red= hot phase 2
Blue= hot phase 3

IIRC 277/480v uses browns and oranges.

here are some pics of my current house water, electric, and gas meter and electrical panel.Two meters one for hot water and one for the rest of electrical power.

electrical panel, the smaller boxes on the left are for a 24v light switching system. All my light switches in the house are 24v and go to relays to turn on and off lights. The advantage of this system is that in the master bedroom there is a small panel that you can turn on or off any switches in the house. This was made by G.E. still in production today.
This is a 200amp panel

This is the water meter in the basement

 

[retro-man]

gas meter outside of house

 

[retro-man]

Ok to new house still under construction. Here is the electric meter. The small black box to the left is the phone interface box. The white cable hanging is for the internet,televison etc.

 

[retro-man]

This is a 400 amp panel. 200amps for basement and first floor. The blue wires are for phone and the black wires are for cable.

 

[retro-man]

This is the panel for the 2nd and 3rd floors plus garage when ever that goes up. 200 amps

 

[retro-man]

This is the gas meter outside

 

[retro-man]

This is the water meter along with the back flow preventer and water filter. Not much copper used in this house only at the begining it is used the rest is all vinyl tubing. Two inch main line coming in which is also vinyl.

Retro-man, your water meter set-ups are of intriguing construction. I've never seen anything like it here. Are you not worried about the longevity of vinyl tubing? In my experience plastic gets weaker over time and with the constant water pressure that may cause problems.

It is unusual here to have gas and electricity meters outside the house and especially so to have them not protected at all. Even the meters for house boats in Amsterdam are placed in cabinets.

I am also amazed to see that the pointer dials are still used for everything: gas, electricity, water. They are rare here. I've only seen them on older water meters. People don't like them.

What is that round attachment on the left side of the second (grey) gas meter?

At work...

Today I have made some pictures at my work. First take a look under my desk.

Now who has the biggest power strip?

 

[mielabor]

As I mentioned yesterday, small water heaters are rather popular here. Take a look under the sink in our pantry.

This water heater has a capacity of 15 litres (4 gallons).

 

[mielabor]

Both dishwasher and water heater are connected to separate circuits.

A. Dishwasher
B. Water heater

Not everything is according regulations. Here we have a "Berlese" set-up for extracting mites from soil or leaf samples.

 

[mielabor]

The wiring will certainly be rejected by a safety inspection. Zip cords galore!

~What is that round attachment on the left side of the second (grey) gas meter?

It is a pressure regulator that adjusts the outflow of gas depending on atmospheric pressure. [Less gas pressure on low pressure bad-weather days, more gas on better high-pressure days, in other words the flames are the same size no matter what the atmosphere is doing]. When the gas meter is indoors, a pipe is added to that device with an outdoor vent.

Outdoor gas meters are "temperatre-compensated" becaue gas contracts in the cold and holds greater amounts of "heat-content" (BTU/calories/kilowatts?) per volume when cold.

The old centrifuge has a 230V 32A connection:

Now some pictures of the Perilex socket that was used by our laboratory washer. It is a 25A rated socket as the opening for the grounding pin in the centre is vertical. More common are 16A rated sockets with horizontal openings (see picture in post# 271651).
