These doorbells usually work on a frequency of about 433 MHz. Inside the "bell-push" unit there is usually a printed circuit board with an "antenna" - being a circuit board "track" connected (soldered) only at one end - usually along the long side of the unit. Because of the size of the unit in...

As stated in Post #1, Hence it is used only to "Charge" a "wireless foot peddle". From this, it would appear that the "wireless foot peddle" contains a Battery, which needs periodic recharging. The (vaguely "medical") "appliance" is the "wireless foot peddle". As far as I can see (from the...

I am sorry to say that the "installation" in the photo is, while obviously messy, also is incorrectly wired. If this is an example of the Electrical Installations in your premises, you may have more "problems" than you now realize!

Since "It is used to charge a wireless foot peddle for a clinic. " (Post #1) the "medical environment" specification may not be of any importance.

A "bootlace/shoelace ferrule" is actually termed an "aglet".

Which seems to be somewhat "overpriced" - in my opinion. Much cheaper to replace the connector.

If you have the skill (or know anyone who has) you could just replace the connector. You will need to check if it is 2.5 mm (which is probable) or 2,.1 mm !!!! A badly worded Amazon "Blurb" (which is NOT unusual) but it says "Negative Sleeve Positive Polarity" which (probably) means that the...

The "superior" design of Socket-Outlets in Australia/New Zealand. where there is no metal Yoke to be Earthed and no metal Box means that there is no need (or ability) to connect the PE conductor to anything except the Earth terminals of the socket-outlet concerned...

You are posting a "different" question on another "thread". To use a "North American" light fixture in France, the wiring and other equipment within the lamp MUST be rated at 230V AC - (Minimum) For ES lamps, it is probable that no adapter will be needed. (However, see Post #3) "Mains...

Looping at the Switch will mean that you will have a Neutral there, if you ever need one for any future "device". Having a Neutral available at the location of a switch is now REQUIRED for "new work" in North America.

Here (again) we have an "newbie" poster (using a [now cheap] High Impendence Digital Voltmeter) discovering "Ghost Voltages" - due to capacitive/inductive coupling, or whatever. Many on this site could write out a description of "why this is so", that one should use a "Low Impedance" meter for...

Modern sealants are quite effective - unless you want to send a ROV down towards the "Titanic" ! The Plug has a "sealing ring" so the two units need to tightly screwed together. The socket connectors actually "leak" - a bit of air. Hence, it would be a good idea to provide additional...

The Items which you have ordered have 3 Keyways which are NOT evenly spaced, so that you can insert the plug into the socket only one way (Roughly speaking, the keyways are at the "points" of an isosceles triangle - NOT an equilateral triangle.) However, since you have ordered the "pair", you...

Here is a small comment relating to faults in heating devices:- Such devices (usually) have an overheating "thermal cutout". This is usually a bi-metal strip device, which resets itself when the temperature drops. However - in addition - they usually have a "Thermal Fuse", which melts when/if...
