The wires on two burners need to be replaced and I don't know what type of
wire to use. I have some regular insulated wire from something else I did
but I am concerned that the heat from the burners will melt this wire, am I
right? The wire says on it: (Essex 10 AWG Type THHN or THWN or MTW E53446*
(UL) Gasoline and Oil resistant II 600 Volt VW-1.). What is the temperature
limit on wire like this and would it be safe to use? Thanks in advance.
I can't tell you the proper wire type but THHN definitely won't do. There
are several types of high temp wire, I used to work on commercial electric
stoves and we generally used a nickel wire with a silicone and fiberglass
covering on it. you can probably call any appliance repair shop and get what
search "high temp wire" or "high temperature wire"
the last old oven i did i just bought a kit at a local appliance service
center. i found it by trying Sears.
PFAH and TFE types with nickel coated copper are rated to 250 C and are
approved for 'leads within apparatus' according to the NEC (Table
310.13). The question is whether 250 C is sufficient for connections
within a stove/oven.

"Within" the over? Nope.
BUT the connections are not made at the truly HOT spots. The inside of the
over might easily be 500F and the space below the burners might be 250F.
The elements are designed so that there is no heat produced within the last
4 to 8" leading to where the connection is made. The connection is made
outside the over and arrangements are made for air to circumlate to keep the
area (relatively) cool. (For the surface burners, efforts are made to
shield the wires an connections from radiation from the hot parts of the
Baring something like an oven fire, 250C wire should be safe.
None of those... you need wire very specially intended to
serve heating elements at the point of connection. These are
generally finely stranded copper with each strand silver
plated, in a very high temperature rated insulation, asbestos
is currently approved in limited applications or a substitute,
This is generally then covered in a woven fiber glass
sheathing... same with the connectors...not the usual
connectors but silver plated rated for high temp application
at resistance heaters, This wire is not a yer local home
depot or usual electrical supply. THHN etc is not even close
to suitable for such applications.. it would be better of
course than THWN etc... but those are not rated for the
proximate connections to heating elements.. just to run i
mildly hot areas..
