Marking circuits

[HayZee518]

Just a thought to whomever is wiring or re-wiring home circuits -- mark your cables with indelible ink pen or adhesive wire markers. It will make troubleshooting the circuit a lot easier IF you need to do troubleshooting. Where the wire exits the panelboard, mark the cable sheath with a #1 about every four feet along the cable jacket. Where the cable goes to a junction box, every wire exiting the junction box should be marked with a #1, that way should anything go wrong with the sub circuit, you'll know its all related to the #1 cable. #2, #3, #4, and so on. Where wires are in a conduit, use adhesive backed wire markers on the individual conductor. Neutrals can be marked with a 2 or L2 because they all end up at the neutral bus anyway. Wire markers can be gotten for any designation or doubled up for higher numbers.

I find it very helpful when wiring a house to write the name of the curcuit on the wire with a pemanent black felt pen, just above where the wire enters the breaker box....Examples: Fridge, HWT(Hot Water Tank), Master Bedroom, ect...

Good afternoon,

An electrician came to my home the other day because of my Heater/ac not working. He said I needed to replace my 90 amp breaker. My question is: Should the system have a 90 amp breaker? That seems awful big. Can you tell me how I can determine myself if the breaker is bad or if the system is overworking?

the breaker will be warm to the touch. other than doing a time over current trip with a test setup - there's no other way
