Strange the difference between the two Countries .
We still sell FP panels and see nothing wrong with them .
I am on my way to the Box store to get 4 FP Ark fault breakers to put in my panel.
Roy are they not federal pioneer up there?
When you need breakers left over from the Ark to fit FP panels you know things are a little behind the times up there Roy. 
Had no idea my answer was cryptic and figured someone would clarify by now but Knob and tube is not allowed to be covered because the whole principle relies on air dissipation of the heat created .
The Hot and neutral are cloth covered and having it in contact with the plastic as shown in post #1 makes it double insulated.
Back in the 20’s when they installed this stuff they were using one outlet per room and today you can bet those conductors are pretty hot if the branch circuit is in use thanks to the probability they are being overtaxed.
Looking at that picture the conductors are also inn direct contact with the wood which also is not allowed as the ceramic tubes and knobs are used specifically to avoid contacts of any kind.
Running romex in conduit is one example of what is meant by double insulated “and not allowed”
Bob… thanks for clarifying.
They are still manufactured and sold in Canada .I am also putting in a new FP panel For my new Generator .
Problems Associated with K&T Wiring:
- Unsafe** modifications** are far more common with K&T wiring than they are with Romex and other modern wiring systems. Part of the reason for this is that K&T is so old that more opportunity has existed for improper modifications.
- The** insulation** that envelopes the wiring is a fire hazard.
- It tends to stretch and sag over time.
- It lacks a grounding conductor. Grounding conductors reduce the chance of electrical fire and damage to sensitive equipment.
- In older systems, wiring is insulated with varnish and fiber materials that are susceptible to deterioration.
Do you have a link ,or name/model, of the panel you’re buying?
Also you misunderstood my previous comment (Ark fault breaker)
Installing NM cable in conduit is specifically allowed by the NEC. It is also required where subject to physical damage.
Sorry about that . This is the panel

I love the USA was down on Friday and bought a water softener $397;00 just looked and the same one in Canada is $598.00
I have.Roy. It just plain wrong to scare people without facts or real problems observed.
You do it your way,
I did what I know is correct, I never scared People ,Thats why Roys Home Inspection is doing very well Thanks .
You can do it wrong if you please Roy.:roll:
I never seen any new ever here anyway, if i see a issue going to report it simple and easy
yep!
Thanks very much for your permision … Roy
It simply is not my business if you choose to use your personal bias as an electrician against knob and tube.
Knob and tube can be safe and is permitted.
Some insurance companies will not insure and that is what I inform my clients about if no other problems with it exist.

[FONT=Arial]Knob and Tube Wiring
[/FONT][FONT=Arial]Many houses constructed before 1950’s have what is called knob and tube wiring.[/FONT]
[FONT=Arial]To determine if your home is wired “knob and tube”, look for ceramic knobs or tubes in which the wire gets attached to, or passes through, joists or studs.
If the knob and tube wiring is not easily visible, you can usually tell by looking at your electrical outlets and switches.
You may only have two prong outlets to plug into. Basically, no ground at each outlet or fixture outlet means knob and tube wiring is present, likewise if you have older push button switches, this is also a good sign you may have knob and tube.
Nowadays, Home owners with knob and tube wiring may find it difficult or impossible to obtain insurance on their home because most insurance companies are not likely to insure a house they perceive as high risk.
Insurance companies usually require a certificate of inspection and compliance from a licensed electrician, that all knob and tube has been removed and replaced with modern 3 wire grounded circuits before it will insure a home that previously had knob and tube wiring.
After the electrician rewires your home, they give you a satisfactory assessment of your home, and the insurance company will consider giving an insurance policy for your house.
[/FONT][FONT=Arial]Overview of Knob-and-Tube Wiring[/FONT]
[FONT=Arial]Knob-and-Tube wiring was the predominant wiring system through the 1920 s and 1930 s; some installations of knob-and-tube wiring continued in houses up until 1950.[/FONT]
[FONT=Arial]There are several distinguishing characteristics of knob-and-tube wiring in comparison to current wiring methods:
Connections between modern wires are completed within enclosed electrical junction boxes. Knob and- tube wiring had visible connections. The wires were spliced and soldered together and then wrapped with electrical tape. These connections are called pig-tail connections because one wire is wrapped several times around the other wire before the two are soldered together.
Ceramic knobs were strategically placed to protect the splice ensuring that inadvertent tugging on the wire would not stress the electrical connection.
While the differences are considerable, there is nothing inherent in knob-and-tube wiring that makes it dangerous.
Knob-and-tube wire, properly installed, is not inherently a problem. While opinions regarding the safety of knob-and-tube wiring vary widely, the concerns are not with the original wiring, but rather with what has happened after the fact.
Older homes with knob-and-tube wiring were often supplied with 60-amp service at the main electrical panel. They were also subject to limited distribution in two forms: (1) limited number of circuits, and (2) limited num-ber of electrical outlets
per room. Both of these factors opened knob-and-tube wiring to potential abuses of the elec-trical system after the initial installation.
[/FONT][FONT=Arial]Improper alterations[/FONT]
[FONT=Arial]Improper alterations are the most consistent problem I find with knob and tube wiring, and they pose a significant safety hazard. Unfortunately from a safety standpoint, the electrical system is one of the few things in a home that can be installed completely wrong and still work.[/FONT]
[FONT=Arial]Additional branches improperly added to the original wiring is one of the common problems I see.
When additional branches or fixtures are added, the fuses protecting the old circuits are likely to blow frequently.
Installing larger fuses is an easy, but unsafe, solution. Oversized fuses allow much more current to flow than originally intended, resulting in additional heat in the conductors. This heat causes the insulation protecting the wire to become brittle, and eventually to disintegrate.

FYI Knob and tube wiring was being installed in some areas into the 1960s
Strange I started the trade on November 22 1951 and never saw any new installations .
I guess i live in a more modern in my part of the country .
