What size cable and breaker for a dedicated 6-20r outlet for a charging system on a 2017 Volvo XC9 t8?
A NEMA code 6-20 R is a 250 volt, 20 amp, straight blade receptacle. In North America it requires a two pole breaker with a common tied handle, to produce 240 volts from a distribution panelboard. No breaker larger than 20 amps can be legally connected to this 20 amp rated receptacle.A #12 copper conductor with an insulation factor of 90 degrees C is rated at 20 amps.
What is a full list of Roman numerals?

Why is 1999 in roman numerals mdccccclxxxxviiii or imm?
Because MDCCCCLXXXXVIIII=IMM (upper case numerals are more preferable). If we place I to both sides of MDCCCCLXXXXVIIII we have IMDCCCCLXXXXVIIIII which when simplified becomes IMM (2000-1) Reverse this procedure to IMM and we go back to MDCCCCLXXXXVIIII (1999).Likewise, 19 in Roman numerals is XVIIII or IXX because they are both of equal value. Once again, if we place I to both sides of XVIIII we have IXVIIIII which when simplified becomes IXX (20-1). Reverse this procedure to IXX and we go back to XVIIII (19).The above method of converting these numerals into subtractive notation or vice versa was used during the Roman era. Evidence and proof of this can be found cast in stone above the entrances into the Colosseum in Rome and in a comprehensive Latin dictionary.David Gambell, Merseyside, England. ____________________________________________________________________1999 is actually MCMXCIX, according to Google Calculator.1000 = M900 = CM90 = XC9 = IXScott Norton, Trumbull, Connecticut, USA
Why is it that when 1666 and 333 are converted into Roman numerals their sum is officially MCMXCIX which does not seem to add up?
1666 and 333 are 1999.MCMXCIX is the same as 1999.1000 = M900 = CM90 = XC9 = IXAnother Explanation:-Because 1666+333 = 1999 and under today's rules governing the Roman numeral system 1999 is officially MCMXCIX in Roman numerals.But: MDCLXVI+CCCXXXIII = MDCCCCLXXXXVIIII (1666+333 = 1999) which the Romans probably simplified the sum to IMM (2000-1) in written format.By simplifying Roman numerals less numerals are needed to represent a given quantity. For instance LXXXVIIIIS (89.5) can be simplified to SXC (100-10.5).Examples of simplification of Roman numerals can be found in the reference book 'History of Mathematics' volume 2 by David Eugene Smith first published in 1925 and ISBN 0486 204 308.The geniune rules governing the Roman numeral system were probably changed during the Middle Ages presumably in order to make it easier to convert Roman numerals into Hindu-Arabic numerals that were being gradually introduced into Western Europe at the time.
What are the numbers from 1 to a 1000000 in Roman numerals?
Notwithstanding todays configuration of Roman numerals inasmuch that there is evidence to suggest that the ancient Romans would have written the equivalent of one to a million as follows:-Units: I, II, III, IIII, V, VI, VII, VIII and VIIIITens: X, XX, XXX, XXXX, L, LX, LXX, LXXX and LXXXXHundreds: C, CC, CCC, CCCC, D, DC, DCC, DCCC and DCCCCThousands: (I), (II), (III), (IIII), (V), (VI), (VII), (VIII) and (VIIII)Tens of thousands: (X), (XX), (XXX), (XXXX), (L), (LX), (LXX), (LXXX) and (LXXXX)Hundreds of thousands: (C), (CC), (CCC), (CCCC), (D), (DC), (DCC), (DCCC) and (DCCCC)Million: (M)To select any numerals simply write them out in descending order and then abridge them whenever possible as in the following examples:-900,000 = (DCCCC) = (CM)90,000 = (LXXXX) = (XC)9,000 = (VIIII) = (IX)900 = DCCCC = C(I) or as CM90 = LXXXX = XC9 = VIIII = IX999,999 = (DCCCCLXXXXVIIII)DCCCCLXXXXVIIII = I(M)Check:-(CM)+(XC) = (XM) = 990,000(XM)+(IX) = (IM) = 999,000(IM)+CM = C(M) = 999,900C(M)+XC = X(M) = 999,990X(M)+IX = I(M) = 999,999Note that numerals within brackets indicate multiplication by a thousand and that the practice of placing a bar above a numeral to indicate multiplication by a thousand was introduced during the Middle Ages along with other rules and regulations governing todays Roman numeral system.QED
