Southwire 12/3 X, Ft. Solid CU MC (Metal Clad) Armorlite Cable - 2d query: would it be ok to have three 15 amp and one 20 amp breaker on this subpanel? As that totals as much as extra than 30 amps but as i said, no more than 20 amps could be drawn at one time.
The feeder breaker inside the upstream subpanel is the disconnecting manner for the downstream subpanel in the case of an indoor subpanel like yours. In case you had been the usage of a major-breaker panel, you could preserve the present main breaker as a further disconnecting method, however in a primary-lug panel like yours, there's no want to add a disconnecting manner that is not required via the nec.
I'm in need of a subpanel in the middle of my save to cord up a few receptacles and lighting fixtures fed from the one hundred amp essential panel which is being fed from the residence. I have now not a great deal experience with wiring as i've only messed with outlets/switches and lights so endure that during thoughts.
Currently, there may be a ten-3 awg twine (black warm, red hot, floor and impartial) from the shop's panel (it's set up to a double-pole 30 amp breaker) to the center of the store (30 toes away) where i need to install the subpanel. The twine was ran by way of my dad years in the past in any other case i might have ran new #6 or #eight cord which would've removed a number of these questions.
The first query: is it okay to use a ten awg copper wire to feed from a 30 amp breaker to a one hundred twenty five amp rated subpanel? I obviously wouldn't be drawing greater than 30 amps from this subpanel as it would just be used to twine up my bedroom (television, low wattage lighting fixtures, 2 receptacles and a low amperage mini refrigerator). It would strength the device room with a pair receptacles to fee batteries, run a pair lights and once in a while strength up a round noticed. (The bed room and tool room would never be active at the identical time.) The subpanel does say the line a, b and n terminals are appropriate for #14 to two/zero so i determine #10 might be best.
